Many-valued coalgebraic logic over semi-primal varieties [PDF]

open access: diamondLogical Methods in Computer Science
We study many-valued coalgebraic logics with semi-primal algebras of truth-degrees. We provide a systematic way to lift endofunctors defined on the variety of Boolean algebras to endofunctors on the variety generated by a semi-primal algebra.

Two Principles in Many-Valued Logic [PDF]

open access: green, 2014
Classically, two propositions are logically equivalent precisely when they are true under the same logical valuations. Also, two logical valuations are distinct if, and only if, there is a formula that is true according to one valuation, and false according to the other.

Duality in finite many-valued logic. [PDF]

open access: bronzeNotre Dame Journal of Formal Logic, 1971
The notion of duality is a familiar one in the two-valued propositional calculus. As there is only one negation connective in the two-valued propositional calculus, the dual of a truth-function can be uniquely determined. In many-valued logics there are many negation connectives.

On transitive modal many-valued logics [PDF]

open access: greenFuzzy Sets and Systems, 2021
This paper is focused on the study of modal logics defined from valued Kripke frames, and particularly, on computability and expressibility questions of modal logics of transitive Kripke frames evaluated over certain residuated lattices. It is shown that a large family of those logics -- including the ones arising from the standard MV and Product ...

Algebraic Analysis of Many Valued Logics [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1958
This paper is an attempt at developing a theory of algebraic systems that would correspond in a natural fashion to the No-valued propositional calculus(2). For want of a better name, we shall call these algebraic systems MV-algebras where MV is supposed to suggest many-valued logics.

On intuitionistic many-valued logics

open access: yesJournal of the Mathematical Society of Japan, 1986
The authors present systems of many-valued logic which stand to classical many-valued logics such as Intuitionistic Logic stands to classical 2- valued propositional logic. The methods are essentially those of Gentzen, but with the notion of sequent generalized to matrices of sequences of formulas.

Many-Valued Logic in the Jewish Short Stories

open access: yesStudia Humana, 2015
Jewish short stories (parables, tales, jokes, etc.) are explained from the viewpoint of many-valued logic. On the basis of some examples, we show, how their contents may be logically interpreted.
