  A multiplicative hyperring is a well-known type of algebraic hyperstructures
which extend a ring to a structure in which the addition is an operation but
multiplication is a hyperoperation. Let G be a commutative multiplicative
hyperring and s,n \in Z^+. A proper hyperideal Q of G is called (weakly)
(s,n)-closed if (0 \neq a^s \subseteq Q) s^s \subseteq Q for a\in G implies a^n
\subseteq Q. In this paper, we aim to investigate (weakly) (s,n)-closed
hyperideals and give some results explaining the structures of these notions.
