Abstract: In modal predicate logic the problem of semanticaI completeness is very nontrivial. Kripke semantics is too weak, and it is not clear how to improve it. In this talk we give a brief overview of the field and present proofs of some recent results on completeness and incompleteness. An earlier version of the talk was given at Workshop on first-order modal and temporal logics (Ljubljana 2023).
