,Correspondence Theory for?Generalized Modal Algebras,s are not the clopen valuations anymore, but values in the set . which are only closed and satisfy additional properties, not necessarily open. This situation is significantly different from existing settings using Stone/Priestley-like dualities, where all admissible valuations are clopen valuations.

,Presburger Büchi Tree Automata with?Applications to?Logics with?Expressive Counting, complexity of the non-emptiness problem for the presented machines. We demonstrate the usefulness of our automata models by polynomially encoding the two-variable guarded fragment extended with Presburger constraints, improving the existing triply-exponential upper bound to a single exponential.

,Towards an?Intuitionistic Deontic Logic Tolerating Conflicting Obligations,gic and it is semantically characterised by a suitable neighbourhood semantics. We further present a simple cut-free sequent calculus for this logic. By means of this calculus we show that logic MIND is decidable and that it satisfies the disjunction property.
