伪NM代数的正规滤子与素滤子

Normal filters and prime filters of pseudo NM-algebras

为建立智能信息处理(近似推理)的数学基础以及逻辑代数自身发展的需要,提出一类新的逻辑代数———伪NM代数.引入了伪NM代数的滤子理论,定义了滤子、生成滤子、正规滤子和素滤子等概念,研究了它们的特征性质,给出了生成滤子的结构,证明了在伪NM代数中素滤子与不可约滤子等价以及极大滤子必是素滤子,建立了伪NM代数的素滤子定理及其推论.它们是NM代数滤子理论相应结果的非交换推广.

In order to establish the mathematical foundation of the intelligent information processing system and develop the logic algebraic theory itself, a new class of logic algebra ——pseudo NM algebra has been proposed recently. This paper introduces and investigates the filter theory of pseudo NM algebra. The notions of filters, generated filters, normal filters and prime filters etc. are defined. Their basic properties are investigated, with the structures of generated filters obtained. We show that prime filters and irreducible filters are equivalent, and that maximum filters must be prime filters. The prime filter theorem of pseudo NM algebra and its some corollaries are established. All these results are the non-commutative generalizations of the corresponding ones of the filter theory of NM algebra.
