Abstract In the year 1971, W. G. Lister [14] introduced the notion of ternary ring. Later in the year 2014, J. R. Castillo and Jocelyn S. Paradero- Vilela [2] introduced the notion of krasner ternary hyperring. In [6] we introduce the notion of multiplicative ternary hyperring. In this paper we study prime hyperideals in a multiplicative ternary hyperring. We obtain some Characterizations of prime hyperideal in a multiplicative ternary hyperring. Lastly we characterize regular strongly distributive multiplicative ternary hyperring with the help of prime hyperideal.

Marty [1] in 1934 and studied extensively by many mathe-

2 208 Md. Salim and T. K. Dutta maticians.in [11] Corsini and Leoreanu-Fotea have collected numerous applications of algebraic hyperstructures from geometry, hypergraph, fuzzy sets and rough sets, cryptography and probabilities. The notion of multiplicative hyperring has been introduced by Rota [13] in which the addition is a binary operation and multiplication is a binary hyperoperation. Krasner s hyperring [3], introduced and studied by Krasner is a hypercompositional structure (S, +, ) where (S, +) is a cannonical hypergroup, (S, ) is a semigroup in which zero element is absorbing and the operation distributes from both sided over addition. In 1971, W.G.Lister[14] introduced the notion of ternary ring and study some important properties of it. According to Lister[14], a ternary ring is an algebraic system consisting of a non-empty set R together with a binary operation, called addition and a ternary multiplication, which forms a commutative group relative to addition, a ternary semigroup relative to multiplication and left, right, lateral distributive laws hold. In 2014, J. R. Castillo [2] introduced ternary hyperrings, called Krasner ternary hyperring. In Krasner ternary hyperring (R, +, ), + is a binary hyperoperation and is a ternary multiplication. In[6] we introduced the notion of multiplicative ternary hyperring. Our notion of multiplicative ternary hyperring differs from the notion of Krasner multiplicative ternary hyperring. In our multiplicative ternary hyperring (R, +, ), + is a binary operation and is a ternary hyperoperation, in which zero element is absorbing zero (i.e 0 R x y = x 0 R y = x y 0 R = {0 R } for all x, y R). Some earlier works on ternary ring and multiplicative ternary hyperring may be found in [4], [5], [7], [8] and [9]. In [12], Procesi and Rota introduced and studied the prime hyperideals in multiplicative hyperrings. The objective of this paper is to introduce and study prime hyperideal in a multiplicative ternary hyperring. We obtain some Characterizations of prime hyperideal of multiplicative ternary hyperring. We also introduce the notions of weak m-system and strong m-system and characterize of prime hyperideal with the help of these notions. Lastly as an application of prime hyperideal we characterize regular strongly distributive multiplicative ternary hyperring. 2 Preliminaries Definition 2.1. By a ternary hyperoperation on a nonempty set H, we shall mean a mapping : H H H P (H) when P (H) is the set of all nonempty subsets of H. For x, y, z H, the image of the element (x, y, z) H H H under the mapping will be denoted by x y z (which is called the ternary hyperproduct of x, y, z).

3 Prime hyperideal in multiplicative ternary hyperrings 209 Definition 2.2. A multiplicative ternary hyperring (R, +, ) is an additive commutative group (R, +) endowed with a ternary hyperoperation such that the following conditions hold : (i) (a b c) d e = a (b c d) e = a b (c d e); (ii) (a + b) c d a c d + b c d; a (b + c) d a b d + a c d; a b (c + d) a b c + a b d; (iii) ( a) b c = a ( b) c = a b ( c) = (a b c) for all a, b, c R; (iv) 0 R x y = x 0 R y = x y 0 R = {0 R } for all x, y R(absorbing property of 0 R ). for all a, b, c, d, e S, where if the inclusions in (ii) are replaced by equalities, then the multiplicative ternary hyperring is called a strongly distributive multiplicative ternary hyperring. Definition 2.3. A multiplicative ternary hyperring (R, +, ) is called commutative if a 1 a 2 a 3 = a σ(1) a σ(2) a σ(3), where σ is a permutation of {1, 2, 3} for all a 1, a 2, a 3 R. A multiplicative ternary hyperring (R, +, ) is commutative if and only if a b c = b a c = b c a for all a, b, c R. Definition 2.4. A nonempty subset ε = {(e i, f i )} n i=1 of R R where R is a multiplicative ternary hyperring is called a left (lateral, right) identity set of R if for any a R, a n i=1 e i f i a(resp. a n i=1 e i a f i, a n i=1 a e i f i ) A nonempty subset ε = {(e i, f i )} n i=1 of R R where R is a multiplicative ternary hyperring is called an identity set if it is a left and a lateral and a right identity set of R An element e of a multiplicative ternary hyperring (R, +, ) is called a unital element of R if a (e e a) (e a e) (a e e). Definition 2.5. Let (S, +, ) and (S, +, ) be two multiplicative ternary hyperrings. Then a mapping f : S S is called a homomorphism(a good homomorphism) if f(a + b) = f(a) + f(b) and f(a b c) f(a) f(b) f(c)(resp. f(a b c) = f(a) f(b) f(c)). Definition 2.6. Let (R, +, ) be multiplicative ternary hyperring. An additive subgroup I of R is called

4 210 Md. Salim and T. K. Dutta (i) a left hyperideal of R if r r x I, for all x I and for all r, r R; (ii) a right hyperideal of R if x r r I, for all x I and for all r, r R; (iii) a lateral hyperideal of R if r x r I, for all x I and for all r, r R; (iv) a two sided hyperideal of R if I is both a left and a right hyperideal of R; (v) a hyperideal of R if I is a left, a right, and a lateral hyperideal of R. Let R be a multiplicative ternary hyperring. If I, J and K are three nonempty subsets of R, then I J K = { a i b i c i : a i I, b i J, c i K}. Proposition 2.7. If (R, +, ) is a multiplicative ternary hyperring and a R, then a r = a R R + {na : n Z} is the right hyperideal of R generated by a. Similarly if (R, +, ) is a multiplicative ternary hyperring and a R, then a m = R a R + R R a R R + {na : n Z} is the lateral hyperideal of R generated by a, a l = R R a + {na : n Z} is the left hyperideal of R generated by a, and a = R R a + a R R + R a R + R R a R R + {na : n Z} is the hyperideal of R generated by a, where Z is the ring of integers. Proposition 2.8. If (R, +, ) is a multiplicative ternary hyperring with a unital element e or with an identity set, and a R then a r = a R R is the right hyperideal of R generated by a. Similarly a m = R R a R R is the lateral hyperideal of R generated by a. and a l = R R a is the left hyperideal of R generated by a, and is the hyperideal of R generated by a, a = R R a R R Remark 2.9. If (R, +, ) is a multiplicative ternary hyperring with a unital element e or with an identity set, then every lateral hyperideal is a left hyperideal as well as a right hyperideal. Hence in a multiplicative ternary hyperring with a unital element e or with an identity set the notions of hyperideal and lateral hyperideal coincide.

5 Prime hyperideal in multiplicative ternary hyperrings Prime hyperideals of multiplicative ternary hyperrings Definition 3.1. A proper hyperideal P of a multiplicative ternary hyperring R is called a prime hyperideal of R if for any three hyperideals I, J, K of R; I J K P implies I P or J P or K P. Example 3.2. Consider the ring of integer Z, then Z is an additive commutative group. Let A = Z\3Z. Now we define a ternary hyperoperation on Z as follows a b c = {a x b y c : x, y A}. Then (Z, +, ) is a multiplicative ternary hyperring. We denote it by (Z A, +, ). Now 3Z is a hyperideal of (Z A, +, ). Let L, M, N be three hyperideals of (Z A, +, ) such that L M N 3Z. Let L 3Z and M 3Z then there exist elements l L and m M but l / 3Z and m / 3Z. Now for any n N, l m n 3Z. This implies that 3 l m n = l x m y n for x, y A. This implies that 3 n. So, n 3Z. Thus 3Z is a prime hyperideal of R. Theorem 3.3. Let (R, +, ) be a multiplicative ternary hyperring and P be a hyperideal of R. Then the following conditions are equivalent : (i) P is a prime hyperideal of R; (ii) a R b R c P, a R R b R R c P, a R R b R c R P and R a R b R R c P implies a P or b P or c P (iii) For any a, b, c R, a b c P a P or b P or c P, (iv) If U, V and W are right as well as lateral hyperideals of R such that U V W P then U P or V P or W P, (v) If U, V and W are left as well as lateral hyperideals of R such that U V W P then U P or V P or W P. Proof. (i) (ii) Suppose P is a prime hyperideal of R and a R b R c P, a R R b R R c P, a R R b R c R P, R a R b R R c P. Now (x 1 a y 1 ) (x 2 b y 2 ) (x 3 c y 3 ) = x 1 (a y 1 x 2 b y 2 x 3 c) y 3 x 1 (a R R b R R c) y 3 x 1 P y 3 P. Since P is a hyperideal of R, ( xi,yi x i a y i ) ( xj,yj x j b y j ) ( xk,yk x k c y k ) P. Hence ( { x i a y i }) ( { x j b y j }) ( { x k c y k }) P. i.e xi,yi xj,yj xk,yk (R a R) (R b R) (R c R) P. Then (R a R + R R a

6 212 Md. Salim and T. K. Dutta R R) (R b R + R R b R R) (R c R + R R c R R) R (a R R b R R c) R+R (a R b R c) R+R (R a R b R R c) R+R R (a R R b R c R)+R (a R R b R c R) R+(R a R b R R c) R R+ R R (a R b R c) R R+R R (a R R b R R c) R R R P R+R P R+R R P +R R P +R P R+P R R+R R P R R+R R P R R P. Since each of the above components are hyperideals of R, by primeness of P, it follows that (R a R+R R a R R) P or (R b R+R R b R R) P or (R c R + R R c R R) P Without loss of generality, suppose that (R a R + R R a R R) P. Then a a a = (R R a+a R R+R a R+R R a R R+{ma : m Z}) (R R a+a R R+R a R+R R a R R+{na : n Z}) (R R a+a R R+R a R+R R a R R+{pa : p Z}) (R a R+R R a R R) P, where m, n, p are integers. Since P is a prime hyperideal of R, a P and hence a P. Similarly if (R b R + R R b R R) P then b P and if (R c R + R R c R R) P then c P. (ii) (iii) Assume (ii) and a b c P for some a, b, c R Then a R b R c = a (R b R) c a b c P ; Similarly a R R b R R c P ; a R R b R c R P ; R a R b R R c P ; Then by using (ii), we find that a P or b P or c P. (iii) (iv) Suppose that U, V and W are three right as well as lateral hyperideals of R such that U V W P. Let U P and V P. Then there exists u U such that u / P and v V such that v / P. Let w W. Now u v w = (R R u+u R R+R u R+R R u R R+{mu : m Z}) (R R v + v R R + R v R + R R v R R + {nv : n Z}) (R R w + w R R + R w R + R R w R R + {pw : p Z}) (R R u+u) (R R v+v ) (R R w+w ) U V W +R R U V W P + R R P P + P P. By (iii) w w P,since u / P and v / P. This is true for all w W. So W P (iv) (i). Suppose (iv) holds and U, V, W be any three hyperideals of R such that U V W P. Then U, V and W are also right and lateral hyperideals of R. Hence by (iv) we have U P or V P or W P. Hence P is prime hyperideal of R. Dually we can prove that (iii) (v) (i). Corollary 3.4. Let (R, +, ) be a multiplicative ternary hyperring with a unital element e or with an identity set. Then a hyperideal P of R is prime if and only if a R R b R R c P implies a P or b P or c P ; Proof. Let P be a prime hyperideal of R. Suppose a R R b R R c P. Then a R b R c a R (e b e) R c a R R b R R c P. Similarly a R R b R c R P and R a R b R R c P. Now by above theorem a P or b P or c P. Similar is the proof when R contains identity set.

7 Prime hyperideal in multiplicative ternary hyperrings 213 Conversely, suppose that a R R b R R c P implies that a P or b P or c P where a, b, c R. Let U, V, W be three hyperideals of R such that U V W P. Let U P and V P. Then there exist elements u U and v V such that u / P and v / P. Now for any w W,u R R v R R w U V W P. By the given condition w P. Then W P. Hence P is a prime hyperideal of R. Corollary 3.5. A hyperideal P of a commutative multiplicative ternary hyperring R is prime if and only if a b c P implies that a P or b P or c P. Proof. Suppose P is a prime hyperideal of a commutative multiplicative ternary hyperring R and a b c P. Now a R (b R c) = a R (b c R) = a (R b c) R = (a b c) R R P R R P i.e a R b R c P, since R is commutative. Similarly a R R b R R c P, R a R b R R c P and a R R b R c R P. Since P is a prime hyperideal of R, now by (ii) of the theorem 3.3, we get a P or b P or c P. Converse is similar to the converse part of Corollary 3.4. Proposition 3.6. Let (R, +, ) be a multiplicative ternary hyperring and P be a prime hyperideal of R. Then for any a, b, c R, the following conditions are equivalent: (i) a b c P a P or b P or c P ; (ii) a b c P b a c P and a c b P. Proof. (i) (ii) It is obvious because P is a hyperideal of R. (ii) (i) Suppose that a b c P, where a, b, c R. Then (a b c) R R P R R P, since P is a hyperideal of R. Now for any y, x R, (a b c) y x P a (b c y) x P (a x b) y c P a x b y c P. This implies that a R b R c P. Again (a b c) R R R R (P R R) R R P R R P. Then for all s, t, x, y R, (a b c) s t x y P a (b c s t x) y P a (y b c s t) x P (a x y) (b c s) t P (a x y t b) c s P (a x y) t (b s c) P (a x y b s) c t P a x y b s t c P (by (ii)). This implies that a R R b R R c P. Similarly we can show that a R R b R c R P and R a R b R R c P. This implies that a P or b P or c P, by theorem 3.3(ii). In [10], N. H. McCoy introduced the notion of m-system as a generalization of multiplicative system and used to characterize prime ideal of rings. Here we generalize this notion for a multiplicative ternary hyperring and characterize prime hyperideal with the help of this notion.

8 214 Md. Salim and T. K. Dutta Definition 3.7. A non empty subset A of a multiplicative ternary hyperring (R, +, ) is called a weak m-system if for any a, b, c A, a R b R c A φ or a R R b R R c A φ or a R R b R c R A φ or R a R b R R c A φ. Definition 3.8. Let (R, +, ) be a multiplicative ternary hyperring. Then a nonempty subset A of R is called a strong m-system if there exist x, y, s, t R such that (a x b y c) A φ or (a x y b s t c) A φ or (a x y b s c t) A φ or (x a y b s t c) A φ. Remark 3.9. Every strong m-system is a weak m-system but the converse may not be true. Proposition Let (R, +, ) be a multiplicative ternary hyperring and P be a hyperideal of R. Then the following conditions are equivalent : (i) P is a prime hyperideal of R. (ii) P c (complement of P in R) is a strong m-system. (iii) P c is a weak m-system. Proof. (i) (ii) Let a, b, c P c. Suppose that (a x b y c) P c = φ, for all x, y R. Then a x b y c P for all x, y R. This implies that a R b R c P. Next suppose that (a x y b s t c) P c = φ for all x, y, s, t R. Then a x y b s t c P for all x, y, s, t R. This implies that a R R b R R c P. Similarly if (a x y b s c t) P c = φ and (x a y b s t c) P c = φ for all x, y, s, t R then we can show that a R R b R c R P and R a R b R R c P respectively. Since P is prime, a P or b P or c P, a contradiction. Thus P c is a strong m-system. (ii) (iii) It is obvious. (iii) (i) Let a R b R c P, a R R b R R c P, a R R b R c R P and R a R b R R c P (A). If possible let a, b, c P c. Since P c is a weak m-system, (a R b R c) P c φ or (a R R b R R c) P c φ or (a R R b R c R) P c φ or (R a R b R R c) P c φ which contradicts (A). So a P or b P or c P. Hence P is a prime hyperideal of R. Theorem If I is a hyperideal of a multiplicative ternary hyperring R and P is a prime hyperideal of R, then I P is a prime hyperideal of I, considering I as a multiplicative ternary hyperring. Proof. Obviously, I P is a hyperideal of I. Let a, b, c I\(I P ). Then a, b, c I and a, b, c / P. Hence a, b, c P c. Since P is a prime hyperideal of

9 Prime hyperideal in multiplicative ternary hyperrings 215 R, P c is a strong m-system. So for some x, y, s, t R, (a x b y c) P c φ or (a x y b s t c) P c φ or (a x y b s c t) P c φ or (x a y b s t c) P c φ. Suppose that (a x b y c) P c φ. Let r 1 (a x b y c) P c. Then r 1 P c. Also a, c P c. Since P c is a strong m-system there exist s, t R, (a s r 1 t c) P c φ. Since r 1 a x b y c, then a s r 1 t c a s a x b y c t c. Therefore (a s a x b y c t c) P c φ. Since s a x I and y c t I, (a I b I c) P c φ. Let r 2 (a I b I c) P c. Then r 2 / P r 2 / I P. Again r 2 a I b I c I. So r 2 I\(I P ). Hence (a I b I c) (I\(I P )) φ. Similarly if (a x y b s t c) P c φ or (a x y b s c t) P c φ or (x a y b s t c) P c φ, then we can show that (a I I b I I c) (I\(I P ) φ or (a I I b I c I) (I\(I P )) φ or (I a I b I I c) (I\(I P )) φ respectively. Thus I\(I P ) is a weak m-system in I. Hence by theorem 3.10 I P is a prime hyperideal of I. Definition A hyperideal I of a multiplicative ternary hyperring (R, +, ) is called a maximal hyperideal of R if I R and for any hyperideal J I of R, I J R J = R. Proposition Let I be a weak m-system of a multiplicative ternary hyperring (R, +, ). If P is a hyperideal which is maximal among all those hyperideals of R which are disjoint from I, then P is a prime hyperideal of R. Proof. If possible, let A, B, C be any three hyperideals of R such that A B C P, but A P, B P and C P. Now P A + P, P B + P and P C + P. Obviously (A + P ) I φ, (B + P ) I φ and (C + P ) I φ. So there exist i 1, i 2, i 3 I such that i 1 = a + p 1, i 2 = b + p 2 and i 3 = c + p 3 for some p 1, p 2, p 3 P, a A, b B and c C. Since I is a weak m-system and i 1, i 2, i 3 I, i 1 R i 2 R i 3 I φ or i 1 R R i 2 R R i 3 I φ or i 1 R R i 2 R i 3 R I φ or R i 1 R i 2 R R i 3 I φ. Suppose that i 1 R i 2 R i 3 I φ (A). Now for all r 1, r 2 R, i 1 r 1 i 2 r 2 i 3 = (a + p 1 ) r 1 (b + p 2 ) r 2 (c + p 3 ) a r 1 b r 2 c + p 1 r 1 b r 2 c + a r 1 p 2 r 2 c + p 1 r 1 p 2 r 2 c + a r 1 b r 2 p 3 + p 1 r 1 b r 2 p 3 + a r 1 p 2 r 2 p 3 + p 1 r 1 p 2 r 2 p 3 P. Thus i 1 R i 2 R i 3 P. So i 1 R i 2 R i 3 I P I = φ which contradicts (A). Similarly if we assume i 1 R R i 2 R R i 3 I φ or i 1 R R i 2 R i 3 R I φ or R i 1 R i 2 R R i 3 I φ we arrive at contradictions. So i 1 R i 2 R i 3 I = φ and i 1 R R i 2 R R i 3 I = φ and i 1 R R i 2 R i 3 R I = φ and R i 1 R i 2 R R i 3 I = φ which contradiction our assumption I is a weak m-system. So A P or B P or C P. Hence P is a prime hyperideal of R.

10 216 Md. Salim and T. K. Dutta Definition 3.14 (proposition 3.8, [7]). Let (R, +, ) be a multiplicative ternary hyperring and I be a hyperideal of R. Then the multiplicative ternary hyperring R/I = {a+i : a R} is called the quotient multiplicative ternary hyperring of (R, +, ) by I, where (a+i)+(b+i) = (a+b)+i and (a+i) (b+i) (c+i) = {p + I : p a b c} for any a, b, c R. Definition Let (R, +, ) be a multiplicative ternary hyperring and I be a hyperideal of R. The mapping π : R R/I, defined by x x + I, is called the projection map of R by I. Theorem The projection map π is a homomorphism of multiplicative ternary hyperrings. Proof. The proof is obvious. Definition A multiplicative ternary hyperring (R, +, ) is called a multiplicative ternary hyperintegral domain if R is a commutative multiplicative ternary hyperring and a 1 a 2 a 3 = 0 implies that a 1 = 0 or a 2 = 0 or a 3 = 0, for all a 1, a 2, a 3 R. Theorem If P R is a hyperideal in a commutative multiplicative ternary hyperring (R, +, ), then P is a prime hyperideal of R if and only if the quotient multiplicative ternary hyperring R/P is a multiplicative ternary hyperintegral domain. Proof. Obviously (R/P, +, ) is a commutative multiplicative ternary hyperring. Let P be a prime hyperideal and a 1 + P, a 2 + P and a 3 + P R/P for a 1, a 2, a 3 R be such that (a 1 + P ) (a 2 + P ) (a 3 + P ) = 0 + P = 0 R/P {y + P : y a 1 a 2 a 3 } = 0 + P = 0 R/P y + P = 0 + P y a 1 a 2 a 3 y P y a 1 a 2 a 3 a 1 a 2 a 3 P a 1 P or a 2 P or a 3 P, since P is a prime hyperideal of R a 1 + P = 0 + P or a 2 + P = 0 + P or a 3 + P = 0 + P Therefore R/P is a multiplicative ternary hyperintegral domain. Converse follows by reversing the above argument. 4 Characterization of regular multiplicative ternary hyperring by prime hyperideals Definition 4.1 ([9]). Let (R, +, ) be a multiplicative ternary hyperring. An element a R is said to be regular if there exists x R such that a a x a.

11 Prime hyperideal in multiplicative ternary hyperrings 217 The multiplicative ternary hyperring (R, +, ) is called regular if all of its elements are regular. Theorem 4.2. Let (R, +, ) be a commutative strongly distributive multiplicative ternary hyperring with a unital element e. Then R is regular if and only if every hyperideal of R, which is maximal with respect to the property of not having a given element in R is a prime hyperideal. Proof. Suppose that R is a regular commutative strongly distributive multiplicative ternary hyperring. Let P be a hyperideal of R, maximal with respect to the property of not containing a given element r R, then r / P (A). If P is not a prime hyperideal of R, then there exist three elements a, b, c R, a b c P, but a / P, b / P and c / P. Consider the hyperideal P + a. Then r P + a. So r p 1 + r i s i a for some p 1 P and r i, s i R. i Again Consider the hyperideal P + b. Then r p 2 + p i q i b for i some p 2 P and p i, q i R. Similarly, the element r is also an element of P + c. So r p 3 + u i v i c for some p 3 P and u i, v i R. Now i r r r (p 1 + i r i s i a) (p 2 + i p i q i b) (p 3 + i u i v i c) P, since R is commutative with a unital or an identity set. Since R is regular, there exists x R, r r x r (r x r) x r = (r r r) x x P, since R is commutative and r r r P. This is contradictions of (A). Hence P is a prime hyperideal of R. Conversely, assume that every hyperideal of R, maximal with respect the property of not having a given element, is a prime hyperideal. Let a R and I a = s R a a s. Using strongly distributive property we can show that I a is a hyperideal of R. Suppose that a / I a. Now Consider the collection M of hyperideals of R as follows: M = {J : J is a hyperideal of R, I a J and a / J}. Since I a M, the collection is nonempty. Then by the Zorn s lemma, M has a maximal element P. This hyperideal P is also maximal with respect to the property not having a. By hypothesis, P is a prime hyperideal. Now a a (a a a) I a P. So q a a P for all q a a a. Since

12 218 Md. Salim and T. K. Dutta a / P, we get q P for all q a a a. This implies that a a a P, since P is prime hyperideal of R, a P, a contradiction. Therefore a I a. This implies that a a a s a a s a for some s R. Thus the strongly distributive multiplicative ternary hyperring (R, +, ) is regular. References [1] F.
