Semihypergroups and properties related to a zero element

Let(s,.) be a semihypergroup with a zero element, say 0. in this paper we study some properties of such semihypergroups depended on zero divisor elements, nilpotent elements, etc. also we will proceed to consider some properties related to a zero element in a demihypergroup S and introduce the property y in particular we prove that the property y immplies the property
