Interpolation properties in the extensions of the logic of inequality
A. V. Karpenko Novosibirsk State University, Mechanics and Mathematics Department, Novosibirsk
Abstract:
We consider the modal logics $wK4$ and $DL$ as well as the corresponding weakly transitive modal algebras and $DL$-algebras. We prove that there exist precisely 16 amalgamable varieties of $DL$-algebras. We find a criterion for the weak amalgamation property of varieties of weakly transitive modal algebras, solve the deductive interpolation problem for extensions of the logic of inequality $DL$, and obtain a weak interpolation criterion over $wK4$.
Keywords:
modal logic $wK4$, modal logic of inequality $DL$, interpolation, deductive interpolation property, weak interpolation property, modal algebra, amalgamation property.
