Czelakowski’s Work on Quasivarietiesis work on: definability of principal congruences, characterizations of relative congruence distributivity, and equational definability of principal meets. In addition, we show how Czelakowski and Dziobiak applied these ideas to produce finite basis theorems. Special emphasis is placed on delivering

Assertional Logics and the Frege Hierarchyhrough the notions of relative point-regularity and relative congruence orderability. We provide new characterizations for the classes of logics within the Frege hierarchy under the underlying assumption of assertionality. In particular, an assertional logic . is fully Fregean if and only if the cla

It does not satisfy full cut elimination but a slightly generalised form of the subformula property holds for it. It is also standard in the sense of satisfying several conditions on rules formulated by Gentze

We give its syntax, semantics, and axiomatics and discuss the relation with other proposals, in particular Belnap and Horty’s ‘branching time and agent choice’ semantics (BT+AC) and Czelakowski’s relational semantics.
