Isomorphism via translation
We observe that the known fact that the difference logic and the hybrid logic with universal modality have the same expressive power on Kripke frames can be strengthened for a far ...

Strong and uniform equivalence of nonmonotonic theories - an algebraic approach
We show that the concepts of strong and uniform equivalence of logic programs eneralized to an abstract algebraic setting of operators on complete lattices. Our results imply char...

On the combinatorial invariance of Kazhdan-Lusztig polynomials
We prove that the Kazhdan-Lusztig polynomials are combinatorial invariants for intervals up to length 8 in Coxeter groups of type A and up to length 6 in Coxeter groups of type B a...

Algebraic and proof-theoretic characterizations of truth stressers for MTL and its extensions
Extensions of monoidal t-norm logic MTL and related fuzzy logics with truth stresser modalities such as globalization and “very true” are presented here both algebraically in ...
