Arithmetical complexity of fuzzy predicate logics – a survey. (English) Zbl 1093.03012
Summary: Results on arithmetical complexity of sets of tautologies and satisfiable formulas of various fuzzy logics (with respect to their standard t-norm-based semantics as well as with respect to their general BL-algebra-based semantics) are surveyed. Some new results are also obtained.
