从*运算出发定义了*滤子,利用格论的相关知识,对公式子集D(Г)进行研究。主要结果是:(1)Luk-Lin-denbaum代数F(S)/~中的*滤子都是(D(Г))形式的;(2)*滤子与MP滤子一致,都是通常意义下的滤子;(3)F(S)/~中的极大*滤子与通常意义下的极大滤子是一致的。
The concept of the * filter is introduced according to the binary operator * in Luk-Lindenbaum algebra. With the corresponding knowledge of lattices, the properties of D(Г) were studied. The main results of this paper are: (1) the * filter is the same style as 〈D(Г)) ; (2) the * filter coincides with the MP filter, both of them are common filters; (3) the maximal * filter in F(S)/- is equal to the maximal filter in common sense.
