An algebraic approach to subframe logics. Intuitionistic case
We develop duality between nuclei on Heyting algebras and certain binary relations on Heyting spaces. We show that these binary relations are in 1–1 correspondence with subframe...

Binary Sequent Calculi for Truth-invariance Entailment of Finite Many-valued Logics
In this paper we consider the class of truth-functional many-valued logics with a finite set of truth-values. The main result of this paper is the development of a new binary sequ...
