On the Intertranslatability of Autoepistemic, Default and Priority Logics, and Parallel Circumscripthe computational complexity of these logics suggest that these logics have very similar expressive power that exceeds that of classical monotonic logic. A refined classification of non-monotonic logics by their expressive power can be obtained using translation functions that satisfy additional requ

An Approach to Query-Answering in Reiter’s Default Logic and the Underlying Existence of Extensions ted approach for deciding whether a default theory has an extension containing a given query. The inherent problem in Reiter’s default logic is that it necessitates the inspection of all default rules for answering no matter what query. Also, default theories are known to lack extensions occasionall

A Mechanised Proof System for Relation Algebra Using Display Logicof any display calculus. The inference rules of Display Logic are coded directly as Isabelle theorems, thereby guaranteeing the correctness of all derivations. Our implementation generalises easily to handle other display calculi. It also provides a useful interactive proof assistant for relation al

Relative Similarity Logics are Decidable: Reduction to FO2 with Equalitynformation. As a side-effect, we obtain a finite model property for such similarity logics. The proof technique consists of reductions into the satisfiability problem for the decidable fragment FO. with equality from classical logic. Although the reductions stem from the standard translation from mo
