In this paper we study the isomorphisms of two ＊-bisimple type A ω2-semigroups such that D^＊ = ^~D） and obtain a criterion for isomorphisms of two such semigroups.
In this paper, we study ＊-simple type A ω2 -semigroups in which D＊= D and D＊｜ES = Md by the generalized Bruck-Reilly extension and obtain its structure theorem.
