  1. Some results on the Kripke sheaf semantics for super-intuitionistic predicate logics.Nobu-Yuki Suzuki - 1993 - Studia Logica 52 (1):73 - 94.
    Some properties of Kripke-sheaf semantics for super-intuitionistic predicate logics are shown. The concept ofp-morphisms between Kripke sheaves is introduced. It is shown that if there exists ap-morphism from a Kripke sheaf 1 into 2 then the logic characterized by 1 is contained in the logic characterized by 2. Examples of Kripke-sheaf complete and finitely axiomatizable super-intuitionistic (and intermediate) predicate logics each of which is Kripke-frame incomplete are given. A correction to the author's previous paper Kripke bundles for intermediate predicate logics (...)

  • Kripke completeness of some intermediate predicate logics with the axiom of constant domain and a variant of canonical formulas.Tatsuya Shimura - 1993 - Studia Logica 52 (1):23 - 40.
    For each intermediate propositional logicJ, J * denotes the least predicate extension ofJ. By the method of canonical models, the strongly Kripke completeness ofJ *+D(=x(p(x)q)xp(x)q) is shown in some cases including:1. J is tabular, 2. J is a subframe logic. A variant of Zakharyashchev's canonical formulas for intermediate logics is introduced to prove the second case.
