A method is presented for analogical reasoning in Automated Deduction. We focus on the abductive aspects of analogy and give a unified treatment for theorems and non-theorems. Abd...
A new version of transition logic is presented. It integrates (dynamic) transitions, which change world states, and classical (static) reasoning, restricted in the paper to Horn l...
Hybrid logics are a principled generalization of both modal logics and description logics, a standard formalism for knowledge representation. In this paper we give the first const...
We give a categorial characterization of how labelled deduction systems for logics with a propositional basis behave under unconstrained fibring and under fibring that is constrai...
In this paper we consider supernormal defaults [Poo88] with a strict partial order defining their priorities [Bre91]. We investigate their relation to minimal or preferential ent...
