Research Statement: I am interested in certain generalizations of prime ideals in commutative rings and prime submodules of unitary modules. Examples of such generalizations are weakly prime ideals (submodules), n-almost prime ideals (submodules) and n-absorbing ideals (submodules). Indeed, I have introduced and studied the concept of almost prime submodules in I am continuously exploring new generalizations of such concepts by considering primary ideas and submodules. I am primarily interested in graded rings and modules. In some of my research papers, I defined and studied almost graded prime ideals and many properties of graded multiplication ideals. In my research endeavors, for some applications of groups and rings theory, I have introduced and studied a method for solving a system of linear equations numerically by exploiting permutation symmetry. I have also introduced QRalgebraic method for approximating zeros of system of polynomials. I am striving for the development of such methods with support of some experts in numerical analysis.

6 I have great interest in the concepts of clean and nil-clean associative rings with identity. Those classes of rings have been introduced and studied extensively during the last 4 decades. I am continuously focusing on generalizations of such rings. I have defined and studied the classes of NR-clean, g(x)-nil clean, weakly g(x)- nil clean and g(x)-precious rings. The theory of algebraic hyperstructures which is a generalization of ordinary algebraic structures has been introduced by Marty(1934). Since then, many researchers have studied the theory of hyperstructures and developed it. Recently, I have started a research concerning hypergroups and hyperrings. Among three kinds of hyperrings, I have focused on a Krasner hyperrings where the addition is a hyper operation and the multiplication is the ordinary operation. What I am looking forward to is studying some applications of this theory in other fields such as geometry, graphs and hypergraphs.
