摘要/Abstract

摘要： 引入了富足半群上fuzzy好同余和fuzzy消去同余的概念, 给出了富足半群上fuzzy好同余的性质和特征。在此基础上, 给出了型A半群上fuzzy好同余的性质。得到了型A半群上的fuzzy好同余为fuzzy消去同余的充要条件。

Abstract: The notions of a fuzzy good congruence relation and a fuzzy cancellative congruence relation on abundant semigroups were introduced, and some properties and characterizations of fuzzy good congruences on such semigroups were given. Some properties of fuzzy good congruences on type-A semigroups were given. Finally, sufficient and necessary conditions for a fuzzy good congruence on a type-A semigroup to be cancellative were proved.

Key words: fuzzy(good) congruence , type-A semigroup, abundant semigroup
