ON STRONGLY Hv-GROUPS

The largest class of hyperstructures is the one which satis es the weak properties; these are called Hv-structures. In this paper we introduce a special product of elements in Hv-group and de ne a new class of Hv-groups called strongly Hv-groups. Then we show that in strongly Hv-groups β = β*. Also we express θ hyperoperation and investigate some of its properties in connection with strongly Hv-groups.
