Homomorphisms between Two Sets of Fuzzy Subsemigroups *

两个模糊子半群集合之间的同态(英文)

Let S and T be semigroups. F(S) and F,(S) denote the sets of all fuzzy subsets and all fuzzy subsemigroups of 5, respectively. In this paper, we discuss the homomorphisms between F(S)(Fs(S)) and F(T)(Fs(T)). We introduce the concept of fuzzy quotient subsemigroup and generalize the fundamental theorems of homomorphism of semigroups to fuzzy subsemigroups.

设S,T是半群,F(S)和F_s(S)分别表示S的所有模糊子集的集合和所有模糊子半群的集合。文中,讨论了F(S)(F_s(S))和F(T)(F_s(T))之间的模糊同态,建立了模糊商子半群的概念,把分明半群的基本同态定理推广到模糊子半群。
