Some results on the Kripke sheaf semantics for super-intuitionistic predicate logics

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 κ1 into κ2 then the logic characterized by κ1 is contained in the logic characterized by κ2. 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 and Kripke frames for intuitionistic modal logics” (Studia Logica, 49(1990), pp. 289–306 ) is stated.
