I n an earlier paper [2], using ZERMELO-FRAENXEL set theory (ZF) as metalanguage, for each ordinal 6 2 1, I introduced a system TTo of transfinite type theory formulated in GENTZEN'S sequentzen style [3]. The notion of sequent and the rules of inference were straightforward generalizations of those
Craig interpolation theorem (which holds for intuitionistic logic) implies that the derivability of X; X โ Y implies existence of an interpolant I in the common language of X and X โ Y such that both X โ I and I; X โ Y are derivable. For classical logic this extends to X; X โ Y; Y , but for intuitio
We generalise the result of [H. Ganzinger, C. Meyer, M. Veanes, The two-variable guarded fragment with transitive relations, in: Proc. 14th IEEE Symposium on Logic in Computer Science, IEEE Computer Society Press, 1999, pp. 24-34] on decidability of the two variable monadic guarded fragment of first
In this article, a cut-free system TLMฯ 1 for infinitary propositional modal logic is proposed which is complete with respect to the class of all Kripke frames. The system TLMฯ 1 is a kind of Gentzen style sequent calculus, but a sequent of TLMฯ 1 is defined as a finite tree of sequents in a standar
