Abstract

We consider varieties generated by finite closure algebras whose canonical relations have two levels, and whose restriction to a level is an “extremal” relation, i.e. the identity or the universal relation. The corresponding logics have frames of depth two, in which a level consists of a set of simple clusters or of one cluster with one or more elements. [ABSTRACT FROM AUTHOR]
