摘要
Abstract
Let E be an equivalence on X and PE(X) is a partial transformation semigroup of preserving equivalence relations determined by the equivalence E.Using the definition of Green's-relations and regular elements, the Green's-relations and regularity on semigroup P2(X)={f∈PE(X)∶|imf|≤2} the subsemigroup of PE(X) are studied and the Green's-relations of semigroup P2(X) is described, and the sufficient and necessary condition of semigroup whose elements are regular are given.关键词
