Furthermore, we evaluate the q-laplace transform of a product of q-bessel functions. Several special cases of our results are also pointed out.. Introduction, Definitions and Preliminaries In the classical analysis, a Parseval-Goldstein type theorem involving the Laplace transform, the Fourier transform, the Stieltjes transform, the Glasser transform, the Mellin transform, the Hankel transform, the Widder-Potential transform and their applications are used widely in several branches of Engineering and applied Mathematics. Some integral transforms in the classical analysis have their q-analogues in the theory of q-calculus. This has led various workers in the field of q-theory for extending all the important results involving the classical analysis to their q- analouges. With this objective in mind, this paper introduces q-analogue of the P-Widder potential transform and establishes certain interesting properties for this integral transform. Throughout this paper, we will assume that q satisfies the condition < q <. The q-derivative D q f of an arbitrary function f is given by D q f)x) = where x. Clearly, if f is differentiable, then fx) fqx) q)x, lim D qf)x) = dfx) q dx. 2 Mathematics Subject Classification. Primary 5A3, 33D5; Secondary 44A,44A2.

In particular, if n Z +, we denote [n] = qn q = qn + + q +. Following usual notation are very useful in the theory of q-calculus: a; q) n = n k= ) aq k, a; q) = ) aq k, a; q) t = a; q) aq t t R). ; q) It is well known that in the literature there are two types of the q-laplace transform and studied in details by many authors.

In the next two sections we introduce a q-analogue of the P-Widder potential transform and establish a Parseval- Goldstein type theorem and its corollaries involving q-analogue of the P-Widder and L 2 -Laplace transforms. Whereas in Section 4, we evaluate the q-laplace transform of a product of basic analogue of the Bessel functions. Several special cases

Definition [2] A function f is q-integrable on [, ) if the series n Z qn f q n ) converges absolutely. We write L qr q ) for the set of all functions that are absolutely q-integrable on [, ), where R q is the set R q = q n : n Z}, that is } L q R q ) := := f : n Z q n f q n ) < f : q } f x) d q x <. Now we introduce the following q-integral transform, which may be regarded as q-extension of the P-Widder potential transform. Definition 2.. A q-analogue of P-Widder potential transform will be denoted P q and defined by the following q-integral: P q f x) ; s} = q 2 In view of 8), 8) can be expressed as P q f x) ; s} = + q x s 2 + q 2 x 2 f x) d qx, Rs) > ). 8) n Z q 2n s 2 + q 2+2n f qn ). 9) Now we prove the following theorem that provide the existence and convergence for the P q -transform: Theorem 2.. If f L q R q ), then the improper q-integral defined by 8) is well-defined. Proof. From 9), we have P q f x) ; s} q 2n + q s 2 + q 2+2n f qn ). n Z q n } Since s 2 + q 2+2n : n Z is bounded, then there exists a K R + such that q n s 2 + q 2+2n < K. Thus, we have P q f x) ; s} K q n f q n ). + q n Z

Multiplying numerator and denominator of K A; t) by + /A), we get K A; t) = A t + /A) q/a; q) A; q) + /A) q t /A; q) q t A; q) = A t /A; q) qa; q) q t /A; q) q t.

This completes to proof. Theorem 3.. The P q -Widder transform can be regarded as iterated q L 2 -Laplace transforms as under: ql 2 q L 2 f x) ; s} ; t} = [2] P q f x) ; t}, 2) provided that the q-integrals involved converge absolutely.

In view of the definition 6), we obtain I = q 2 ql 2 ; t 2 + q 2 x 2) /2 } xf x) d q x. On setting fx) = and s = t 2 + q 2 x 2) /2 in 7) and then using the formula L q 2; s 2 } =, we get the desired result s2 I = [2] q 2 = [2] P q f x) ; t}. xf x) t 2 + q 2 x 2 d qx Corollary 3.. If 2 < α < then the following formula holds: P q x α ; t} = B q2 + α/2; α/2) [2] q 2 K ; + α/2) K /t 2 ; α/2) tα, 22) where KA; t) is given by 4). Proof. On setting fx) = x α and make use of the known result due to Uçar and Albayrak [2], namely ql 2 x α ; s} = Γ q 2 + α/2) ) q 2 α/2 [2] K /s 2 ; + α/2) s α+2 2 < α < ), the identity 2) of Theorem 3. give rise to P q x α Γ q 2 + α/2) ; t} = [2] ql ) }} q 2 α/2 2 [2] K /s 2 ; + α/2) s α+2 ; t = Γ q 2 + α/2) q 2) α/2 s α 2 } ql 2 K /s 2 ; + α/2) ; t.

Hence P q x α ; t} = Γ q 2 + α/2) q 2) α/2 K ; + α/2) [2] t 2 ; q 2 q 2n q n ) α 2 t 2 ; q 2) ). n n Z

In the following theorem, we establish a Parseval-Goldstein type theorem that involving q-analogue of the P-Widder and L 2 -Laplace transforms: Theorem 3.2. If P q and q L 2 denote q-analogues of the P-Widder and L 2 -Laplace transforms, then the following result holds true: x q L 2 f y) ; x} q L 2 g z) ; x} d q x = [2] provided that the q-integrals involved converge absolutely. yf y) P q g z) ; qy} d q y, 23) Proof. Using the definition of the q L 2 -transform 6), the left-hand side of 23) say J) yields to J = q 2 x q L 2 g z) ; x} ye q 2 x 2 y 2) } f y) d q y d q x. Changing the order of the q-integration, which is permissible by the hypothesis, we find that J = q 2 yf y) xe q 2 q 2 y 2 x 2) } ql 2 g z) ; x} d q x d q y. In view of the definition 6) and the result 2) of Theorem 3., the above relation reduces to the desired right-hand side of 23). Corollary 3.2. We have xh x) q L 2 f y) ; x} d q x = provided that the q-integrals involved converge absolutely. yf y) q L 2 h x) ; qy} d q y, 24) Proof. The identity 24) follows immediately after letting h x) = q L 2 g z) ; x} in the relation 23). Corollary 3.3. With due regards to convergence, we have q 2 P q ql 2 g u) ; x} ; q 2 z } = q L 2 P q g u) ; qy} ; qz}. 25)

To prove 25), we set f y) = e q 2 y 2 z 2), then we get ql 2 f y) ; x} = q 2 ye q 2 x 2 y 2) e q 2 q 2 z 2 y 2) d q y = [2] x 2 + q 2 z 2. 26) Substituting 26) into the identity 23) of Theorem 3.2, we obtain x x 2 + q 2 z 2 q L 2 g u) ; x} d q x = ye q 2 q 2 z 2 y 2) P q g u) ; qy} d q y q 2 q 2 P q ql 2 g u) ; x} ; q 2 z } = q L 2 P q g u) ; qy} ; qz}. Similarly, if we set f y) = E /q 2 y2 z 2 ) in Theorem 3.2 and using the wellknown q-exponential identity e q 2q 2 x) = E /q 2x) we find that ql 2 E /q 2 y2 z 2 ) } q 2 ; x = q L 2 eq 2 q 2 z 2 y 2) ; x } = [2] x 2 + q 2 z 2 27) Substituting 27) into 23) we obtain x x 2 + q 2 z 2 q L 2 g u) ; x} d q x = and finally we have q 2 P q ql 2 g u) ; x} ; q 2 z } = Theorem 3.3.

In this section, we propose to add one more dimension to this study by introducing a theorem which give rise to q-laplace image under the L q operator 3) for a product of q- Bessel functions. The third q-bessel function is defined by Jackson and in some literature it is called Hahn-Exton q-bessel function. For further details see [5].
