摘要
本文定义了一类π－正则半群，即π－纯正Ｌ＊－幂幺半群，给出了此类半群为弱Ｃｌｉｆｏｒｄπ－正则半群，ＧＶ－半群，π－逆半群的充分必要条件。
This paper introduced the
concept of a π orthodox L * unipotent semigroup and determined that the necessary and
sufficient conditions for this class of semigroups were weak Cliffordian π regular semigroups,GV
semigroups,and π inverse semigroups.
