Complexity issues in Basic Logic
|Title:||Complexity issues in Basic Logic|
We survey complexity results concerning a family of propositional many-valued logics. In particular, we shall address satisfiability and tautologousness problems for Hájek's Basic Logic BL and for several of its schematic extensions. We shall review complexity bounds obtained from functional representation results, as well as techniques for dealing with non-trivial ordinal sums of continuous t-norms.
