In their recent celebrated paper, Hanks and McDermott presented a simple problem in temporal reasoning which showed that a seemingly natural representation of a frame axiom in nonmonotonic logic can give rise to an anomalous extension, i.e., one which is counter-intuitive in that it does not appear

β¦ Synopsis
Default logic is a prominent rigorous method for reasoning with incomplete information based on assumptions. It is a static reasoning approach, in the sense that it doesn't reason about changes and their consequences. On the other hand, its nonmonotonic behavior appears when changes to a default theory are made. This paper studies the dynamic behavior of default logic in the face of changes. We consider the operations of contraction and revision, present several solutions to these problems, and study their properties.

Bondarenko et al. have recently proposed an abstract framework for default reasoning. Besides capturing most existing formalisms and proving that their standard semantics all coincide, the framework extends these formalisms by generalising the semantics of admissible and preferred arguments, origina
