Semihypergroups obtained by merging of 0-semigroups with groups

We consider the class of 0-semigroups (H,*) that are obtained by adding a zero element to a group (G,?) so that for all x,y ? G it holds x * y ? 0 => x * y = xy. These semigroups are called 0-extensions of (G,?). We introduce a merging operation that constructs a 0-semihypergroup from a 0-extensi...
