Design complete sequential calculus for continuous fixpoint temporal logic,culus for temporal logic under consideration to finitary one. As result of the reduction we can prove completeness and obtain the cut-free sequential calculus for temporal logic under consideration. The reduction present some way for searching so called invariant formulas.

Logical omniscience and classical logic,ordinary language syntactically different expressions in general are not intersubstitutable in the scope of verbs of propositional attitude. It thus seems that logics of knowledge and belief should not be subject to Leibniz‘s Law. In the literature (e.g. Rantala [1982., 1982.], Wansing [1990]) we in

Deriving inference rules for terminological logics,oretical investigations with issues arising in the actual implementation of terminological representation systems. We propose to use inference rules, derived via the sequent calculus, as a new method for specifying terminological inference algorithms. This approach combines the advantages of the tab

Ovulation

Linear proofs and linear logic,spired by this idea in [7] a similar approach based on Linear Logic was presented. The present paper analyses the relationship of these two approaches and shows to which extent they are equivalent and where they differ.

Modellings for belief change: Base contraction, multiple contraction, and epistemic entrenchment (py syntax-based belief changes that are governed exclusively by the structure of the belief base. In answering the question whether this kind of belief change can be reconstructed with the help of something like an epistemic entrenchment relation in the sense of G?rdenfors and Makinson [8], we extrac

A framework for default logics,iants from a knowledge representation point of view. We then exploit this framework to generalize Brewka‘s work on cumulative default logic, and to give an operational definition of extensions. Proof theoretical and semantical aspects are investigated.
