hyperideals of (finite) general hyperrings

A general hyperring is an algebraic hypercompositional system (r,+,·) with two hyperoperations ”+& and ” · ”, such that for all x,y ∈ r, x + y and x · y are non-empty subsets of r, and r satisfies the axioms similar to a ring. we introduce and study hyperideals of a general hyperring. in this regards, we construct a connection between classical rings and general hyperrings, specifically, we extend a ring to a general hyperring in nontrivial way. moreover, a way to construct a general hyperring from set are given. also, we concentrate on an important class of general hyperrings, which is called krasner hyperrings, and discuss on their hyperideals. finally, the set of all hyperideals of a finite general (resp. krasner) hyperring are considered and its hyperideals are investigated.
