Many-valued logics are standardly defined by logical matrices. They are truth-functional. In this paper non truth-functional many-valued semantics are presented, in a philosophica...
The problem of approximating a propositional calculus is to nd many-valued logics which are sound for the calculus (i.e., all theorems of the calculus are tautologies) with as few...
The paper provides a recipe for adequately representing a very inclusive class of finite-valued logics by way of tableaux. The only requisite for applying the method is that the o...
