Regularity and Green's Relations for a Semigroup of Transformations Preserving an Equivalence Relation
摘要
Abstract
Let X be a set with ∣X∣ >3 ,TX the full transformation semigroup on X,£ an equivalence relation on X andTE(X) the subsemigroup of Tx determined by E which satisfies V∨ (x,y) ∈E,(f(x) f(y)) ∈E. Let T2(X) be a subsemigroup of TE(X) and V/e T2(X), ∣f(X) ∣ ≤2. The Green's relations and regular elements in the semigroup T2(X) are described and discussed.关键词
