Synopsis:

The course contains a presentation of mathematical fuzzy logic (propositional and predicate) as a formal many-valued logical system, problems of axiomatizability, its semantics based on the notion f a continuous t-norm.

Requirements:

knowledge of basic logical notions (conjunction etc.), ability of mathematical reasoning.

Syllabus of lectures:

Continuous t-norm and its residuum as the standard semantics of conjunction and mplication, residuated lattices, BL-algebras, general semantics. The basic propositional fuzzy logic BL, three stronger logics: Lukasiewicz, Gödel and product logic. Examples of formal proofs. Problems of decidability.

Corresponding predicate logics, double semantics. Examples of formal proofs. Problems of decidability.

Syllabus of tutorials:
Study Objective:

to help the student to replace the usual understanding of fuzzy logic (as arbitrary use of fuzzy sets) by the deeper treatment of fuzzy logic as a particular many-valued (formal) propositional and predicate logic with its axioms, formal proofs and well-defined sémantice. Clarify the relation of fuzzy logic to vagueness, probability and modal logic.
