摘要:
将WBR0-代数的条件进行两种不同形式的弱化,建立了模糊BR0-代数(FBR0-代数)结构和正则BR0-代数(RBR0-代数)结构,讨论了其中的相关性质.证明了:正则BR0-代数是模糊BR0-代数,模糊BR0-代数和FI-代数是相同代数结构,正则BR0-代数和正则FI-代数是相同代数结构.分别构造了非正则BR0-代数的模糊BR0-代数和非WBR0-代数的正则BR0-代数,从而阐明了模糊BR0-代数、正则BR0-代数、WBR0-代数的相互蕴涵关系和相对独立性.

Abstract:
By weakening the conditions of the WBR0-algebras with 2-kinds of different forms, the fuzzy BR0-algebras (FBR0-algebras) and the regular BR0-algebras(RBR0-algebra) were built and then their properties were discussed.It is proved that a RBR0-algebra is a FBR0-algebra,FBR0-algebras has the same algebraic structure with FI-algebrasand RBR0-algebras has the same algebraic structure with regular FI-algebras.It is also showed that FBR0-algebra is not a RBR0-algebra and RBR0-algebra is not a WBR0-algebra by constructing a example respectively, which explains that there exist the implication relation and relative independence between 3-kinds of algebras.
