Some types of implicative ideals

Comment.Math.Univ.Carolinae 39,2 (1998) 219-225.

Abstract:This paper studies basic properties for five special types of implicative ideals (modular, pentagonal, even, rectangular and medial). The results are used to prove characterizations of modularity and distributivity.

Keywords: implicative ideals, modular ideals, pentagonal ideals, even ideals, rectangular ideals, medial ideals, modularity, distributivity
