Abstract

In this paper, two types of gradational L-type lattice-valued propositional logic L"v"p"l, with truth values in a lattice implication algebra are introduced and some fundamental questions of them such as semantics, syntax and compactness are investigated, and where the L-type @a-Soundness Theorem, (@a, @b)-Completeness Theorem, (@a, @b)-Consistent Theorem and (@a, @b, @q)-Deduction Theorem are also proved.
