在极大滤子定义基础上引入极大并滤子概念,进而给出分配格的一个新的内部刻画,并证明了其存在性定理.最后,讨论了Heyting代数中极大并滤子及其相关性质.
The concept of maximal join-filters is introduced based on maximal filters. A new intrinsic characterization of dis-tributive lattices is obtained. The existence of maximal join-filters is proved. Lastly,the relative properties of maximal join-filters in Heyting algebras is discussed.
