Fuzzy good congruences on type-A semigroups
Chunhua Li · Journal of Shandong University · 2008
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.
