Subsemigroup〈E(S)〉of a GV-inverse Semigroup
LI Wei-xia · Journal of Qingdao University · 2008
The subgroup 〈E(S)〉 generated by the set of idempotents of a semigroup S plays an important role in the study of the congruence on S.When S is a GV-inverse Semigroup,it is proved that r(t)∈E(S),for any t∈〈E(S)〉,〈E(S)〉 is a π-regular semigroup and GV-inverse Semigroup.
