Also we proved distributivity using translation .we have defined annihilators and ideals of Poset of Subhypergroup of a hyper group. we proved some sufficient condition for Poset to be a distributive Poset.

This theory has been subsequently developed by Corsini[5],Mittas[3]and by various authors, Basic definitions and propositions are found in [4] .M Tarauceanu contributed to the study of Poset of Subhypergroup of a hyper group .He had drawn conclusions on Poset (Sub(H),)and he had also given some open problems on above stated Poset and lattices . In this section, we study the distributivity of Poset of Subhypergroup of a Hyper group Principle Filter and we study the necessary condition for Poset to be a Distributive Poset Using the Concept of Translation,[7]. Finally we study the Annihilators [6] and ideals of Poset of Subhypergroup using Principle Filter. Notations and definitions are used from [4],[2],[6]. 1.Basic Notations and Terminology: Definition 1.1 [4]: A hyper Operation on H is a map : H x H P*(H). Definition 1.2[4]: If the hyper operation” “is associative and a H=H=H a, then (H, ) is a Hyper group. Definition 1.3 [4]: A hyper group (H, is called a join space if “ ” is commutative and a/b c/d a d b .where a/b ={x H/a b x} 2. Sub(L)=F(L) Example 2.1[4] : Let (L; л;v) be a complete lattice and, for every a 2 L, denote by F(a) the principal Filter of L generated by a (F(L)={x є L/a ≤ x})Then L is a join space under the hyper operation a ◦ b = F(a˄b); for all a; b є L. Proposition 2.2[4]: For the join space(L, ◦ ) given by the following equality holds Sub(L)=F(L)={F(a)/a єL} That is the subgroup of L coincides with the principal filter of L. In particular Sub(L) is a lattice anti isomorphic to L. Definition 2.3: Let Sub(L)=F(L) be a Poset. If F(A) Sub(L)=F(L) then we will denote L(F(A))={f(x) є Sub(L),f(x)≤f(a) for all f(a) є F(A)}
