摘要
本文研究更为广泛的富足半群———W0 -富足半群。我们引入一种新的等价关系——— + + -格林关系 ,讨论了它的一系列性质。定义了一类半群 ,称为W0 -富足半群 ,给出它的等价刻划。
In this paper, We study a more universal abundant semigroup than abundant semigroup. It is W 0-abundant semigroups.We introduce another new equivalence, ++-Green ,s relation on semigroups. Some properties of ++-Green ,s relations are discussed. We define a class of semigroups called W 0-abundant semigroups and give the characterization of W 0-abunddant semigroups.
