摘要
本文用集合套为工具对Fuzzy环进行了重新刻划。主要讨论了以下问题:用集合套定义了Fuzzy环,Fuzzy理想,Fuzzy商环等概念,说明了这种定义与文献[4,5]中的定义是一致的,并讨论了一些基本性质,用集合套简便地证明了Fuzzy环的同态基本定理及有关的同构定理,不需要限制具有“sup”性质;最后研究了Fuzzy商子环和Fuzzy子环积的性质及同构定理.
In this paper the fuzzy rings are characterised again by the nested set and the following problems are discussed: using nested set to redefine the concepts of fuzzy rings, fuzzy ideals and fuzzy quotient rings and the definitions given are proved to be the same as in references[4,5],using nested set to prove in a simple way the homomorphism theorem and some isomorphic theorems in fuzzy rings, discussing the products of fuzzy rings and fuzzy quotient subrings.
