Three complexity problems in quantified fuzzy logic
Studia Logica 68 (1):143-152 (2001)
Abstract
We prove that the sets of standard tautologies of predicate Product Logic and of predicate Basic Logic, as well as the set of standard-satisfiable formulas of predicate Basic Logic are not arithmetical, thus finding a rather satisfactory solution to three problems proposed by Hájek in [H01].My notes
