UM CÁLCULO DE SEQUENTES A PARTIR DO SISTEMA TRIVALENTE E FRACAMENTE INTUICIONISTA I1

The logic I1, a three-valued system with an weakly-intuitionistic character, was introduced by Sette and Carnielli in 1995 via axiomatic (Hilbertian) system. The aim of this paper is to present this system in a logical formalism by sequent calculus, called GI1, which presents itself as a theorem pro...

Descrição
Resumo:The logic I1, a three-valued system with an weakly-intuitionistic character, was introduced by Sette and Carnielli in 1995 via axiomatic (Hilbertian) system. The aim of this paper is to present this system in a logical formalism by sequent calculus, called GI1, which presents itself as a theorem proof system, characterized as an algorithm, being more applicable from a computational point of view, by means of the dualization of the analytical tableaux TI1. Furthermore, the deductive equivalence between the sequent system GI1 and the Hilbertian system I1 is presented.
