Abstract: In the last years many logics of nonmonotonicity have been developed
using various different formalisms and axiomatizations which
makes them very difficult to compare. We develop a classification
scheme for these logics using only a few simple concepts and axioms
based on conditional logics, properties of partial pre-orders of possible
worlds and centering assumptions. Our framework (the P-Systems)
allows us to discuss the similarities, main differences and possible extensions
of these... (Update)
