In Iemho (J. Symbolic Logic, to appear) we gave a countable basis V for the admissible rules of IPC . Here, we show that there is no proper superintuitionistic logic with the disjunction property for which all rules in V are admissible. This shows that, relative to the disjunction property, IPC is m
## Abstract In this paper we propose a Kripkeโstyle semantics for second order intuitionistic propositional logic and we provide a semantical proof of the disjunction and the explicit definability property. Moreover, we provide a tableau calculus which is sound and complete with respect to such a s
We prove that the intuitionistic sentential calculus is L-decidable (decidable in the sense of Lukasiewicz), i.e. the sets of theses of Int and of rejected formulas are disjoint and their union is equal to all formulas. A formula is rejected iff it is a sentential variable or is obtained from other
