Jan Łukasiewicz
Jan Łukasiewicz (1878 - 1956) Polish mathematician and logician mainly concerned with logic in mathematics probably best known for the three-valued logics, the Polish notation, the law of excluded middle
and the axiomatizations of much classical propositional logic
. He studied at the University of Lwów, earning doctorates in mathematics and philosophy in 1902. In 1919 he was Minister of Education in Poland. After WWII, he was exiled to Belgium. Arguably, the 3-valued logics named after him was the first published report of a non-Boolean, or non-Chrysippean logic (with only two logic values, ‘true’ or ‘false’, in the Chrysippean case). Subsequently, Łukasiewicz logic algebras
were constructed by Grigore Moisil in 1940-1945 to define ‘nuances’ in logics, or many-valued logics, as well as 3-state control logic (electronic) circuits
. Łukasiewicz-Moisil () logic algebras were defined axiomatically after 1969 as n-valued logic algebra representations and extensions
of the Łukasiewcz (3-valued) logics; then, the universal properties
of
categories
of -logic algebras (http://planetmath.org/AlgebraicCategoryOfLMnLogicAlgebras) were also investigated and reported in a series of recent publications. Recently, several modifications of -logic algebras are under consideration as valid candidates for representations of quantum logics
, as well as for modeling non-linear biodynamics in genetic ‘nets’ or networks, as well as in single-cell organisms, or in tumor growth.
