Undecidable iterative propositional calculus
Grigoriy V. Bokov
In this paper, we consider iterative propositional calculi, which are finite sets of propositional formulas together with the rules of modus ponens and weak substitution (when form…

On the number of variables in undecidable superintuitionistic propositional calculi
Grigoriy V. Bokov
In this paper, we construct an undecidable 3-variable superintuitionistic propositional calculus, i.e., a finitely axiomatizable extension of the intuitionistic propositional calcu…

Undecidable problems for propositional calculi with implication
Grigoriy V. Bokov
In this article, we deal with propositional calculi over a signature containing the classical implication with the rules of modus ponens and substitution. For these calculi w…
