Abstract
A B 4-valued propositional logic will be proposed in this paper which there are three unary logical connectives ~1, ~2, ¬ and two binary logical connectives ∧, ∨, and a Gentzen-typed deduction system will be given so that the system is sound and complete with B 4-valued semantics, where B 4 is a Boolean algebra.
