We investigate the relationship between recursive enumerability and elementary frame definability in first-order predicate modal logic. On one hand, it is well known that every first …

We obtain an effective embedding of the classical predicate logic into the logic of partial quasiary predicates. The embedding has the property that an image of a non-theorem of the …

The joint logic of problems and propositions QHC introduced by SA Melikhov, as well as intuitionistic modal logic QH4, is studied. An immersion of these logics into classical first …
Проблемы укладки домино являются удобным инструментом оценки алгоритмической сложности задач, возникающих в различных разделах математики, в том числе в …
The question about recursive enumerability of modal predicate logics defined by non first- order definable classes of Kripke frames is considered. It is proved that logics of classes of …
