保持等价关系的变换半群的一些结果
Some results on transformation semigroups that preserve an equivalence
摘要
Abstract
For transformation semigroups that preserve an equivalence,sufficient and necessary conditions are given,in which the Green relations L,R,H and Green *-relations L*,R*,H* are compatible.The left(right,completely)regularity are characterized,and equivalent descriptions are obtained that idempotent(regular,abundant)elements form a subsemigroup.关键词
