Finiteness Conditions For Union of Two Finite Semigroups and Upper Rank of B(G; n)

Melis Minisker


In this paper we consider finiteness conditions of union of two finite semigroups with empty intersection. We define a special binary operation on the union of two finite semigroups. We also determine the upper rank of the Brandt semigroup


r4(B(G; n)).
