There are logics where necessity is defined by means of a given identity connective: $${\square\varphi := \varphi\equiv\top}$$ := ($${\top}$$ is a tautology). On the other hand, in many standard modal logics the concept of propositional identity (PI) $${...
A surprising result of Pitts (1992) says that propositional quantifiers are definable internally in intuitionistic propositional logic (IPC). The main contribution of this paper is to provide a formalization of Pitts’ result in the Coq proof assistant,...
In this paper we investigate the connections between quantifier elimination, decidability and Uniform Craig Interpolation in Δ-core fuzzy logics added with propositional quantifiers. As a consequence, we are able to prove that several propositional ...
