A Criterion for Admissibility of Inference Rules in Some Class of S4-Logics Without the Branching Property

  • E. M. Golovanova


We consider a finitely approximable modal S4-logic without the branching property. Although Rybakov's criterion is inapplicable, using his method we manage to obtain an algorithmic criterion for admissibility of inference rules in a given logic.
