A short survey of main historical developments of systems of fuzzy logic in narrow sense, today under the umbrella of the discipline called Mathematical Fuzzy Logic, arising from teducation-teaching-fuzzy_math-fuzzy_mathematics-fuzzy_set_theory-mathematicians-math_teacher-rmon4614_low.jpghe birth of Zadeh’s fuzzy sets in 1965. Particular attention is devoted to show how the tools of mathematical logic have allowed to define logical systems which form the core of Mathematical Fuzzy Logic and allow for a formalization of some topics included in Zadeh’s agenda spanning from fuzzy sets to approximate reasoning and probability theory of fuzzy events.

Brazil and mangoes

IMG_20180203_143956_261.jpgFirst week in Campinas (São Paulo, Brazil) for a one month visit to the Centre for Logic, Epistemology and History of Science. The work here is focusing on determining a term-equivalent (unary and easier to interpret) fragments of Lukasiewicz finite-valued logics which could capture paraconsistent properties. It’s funny, some arithmetic, prime numbers, and little bit of algebra at work. When we do not work, I use to have a walk. It’s summer here and wherever I look, I see mangoes.
