Based on a (total) pre-order on a set, we axiomatize the Egli-Milner order on the power set and show how it is related to the Lewis order. Moreover, w......
A finitely alternative normal tense logic T-n,T-m is a normal tense logic characterized by frames in which every point has at most n future alternativ......

We consider, in the context of an MS-algebra L, the ideals I of L that are kernels of L. We characterize two kinds of de Morgan algebras: the class Bo......

The global consequence relation of a normal modal logic Lambda is formulated as a global sequent calculus which extends the local sequent theory of La......
The minimal weakening N0 of Belnap-Dunn logic under the polarity semantics for negation as a modal operator is formulated as a sequent system which is......
