## Abstract We present sequent calculi for normal modal logics where modal and propositional behaviours are separated, and we prove a cut elimination theorem for the basic system K, so as completeness theorems (in the new style) both for K itself and for its most popular enrichments. MSC: 03B45, 03

Semantics are given for modal extensions of relevant logics based on the kind of frames introduced in I-7]. By means of a simple recipe we may obtain from a class FRM (L) of unreduced frames characterising a (non-modal) logic L, frame-classes FRM m (L:M) eharacterising conjunctively regular modal ex
In this article, a cut-free system TLMω 1 for infinitary propositional modal logic is proposed which is complete with respect to the class of all Kripke frames. The system TLMω 1 is a kind of Gentzen style sequent calculus, but a sequent of TLMω 1 is defined as a finite tree of sequents in a standar
We view models of rewrite theories enriched with observations coalgebraically. This allows us on the one hand to use "off the shelf" logics for coalgebras to specify and, on the other hand, to verify properties of rewriting programs and to obtain results about the expressive power of such languages.
