摘要
Gomes在1985年利用同余对刻画了正则半群上的左逆半群同余.特别地,她给出了左逆半群上任一同余的刻画.本文则给出了左逆半群上任一同余的另一种刻画.
Gomes in 1985 characterized left inverse semigroup congruences on a regular semigroup by using congruence pairs. In particular, a characterization of congruences on a left inverse semigroup was given. In this paper, a new characterization for congruences on left inverse semigroups is obtained.
