Abstract: Given a lattice L, an L-modalized propositional logic will be proposed in which each element a ∈ L is associated with a modality [a], and a Gentzen-typed deduction system
GL
will be given so that the the system is sound and complete with the L-valued semantics, where [a] A means that the truth-value of formula A is a. Moreover, the distributivity and modularity of
GL
will be discussed.
Keywords: The Belnap logic, the modality, lattice, distributivity of a deduction system, modularity
