Loop Formulas for Circumscription
Clark's completion is a simple nonmonotonic formalism and a special case of several nonmonotonic logics. Recently there has been work on extending completion with "loop ...

A Logic for Reasoning about Upper Probabilities
We present a propositional logic to reason about the uncertainty of events, where the uncertainty is modeled by a set of probability measures assigning an interval of probability ...

An Axiomatization of a First-order Branching Time Temporal Logic
: We introduce a first-order temporal logic for reasoning about branching time. It is well known that the set of valid formulas is not recursively enumerable and there is no fini...
