Some Classes of Fuzzy Sub-semigroups on Inverse Semi-groups
Shuping Gao · Journal of Jilin University(Science Edition) · 2006
On inverse semi-groups,the fuzzy normal sub-semigroup and fuzzy quotient sub-semigroup are defined via some special fuzzy relation by using fuzzy congruence relation on set.Some basic properties of those fuzzy congruence relation,which are defined by fuzzy relation,were studied,fuzzy normal quoitent sub-semigroup R and fuzzy congruence relation μ_R on inverse semi-group S/ρ were obtained by fuzzy congruence relation β.
