Abstract: In this paper we present a labelled proof method for computing nonmonotonic consequence relations in a conditional logic setting. The method exploits the strong connection between these deductive relations and conditional logics, and it is based on the usual possible world semantics devised for the latter. The label formalism KEM, introduced to account for the semantics of normal modal logics, is easily adapted to the semantics of conditional logic by simply indexing labels with formulas. The...

...# within a framework of conditional logic. It seems thus reasonable to view it as the conditional counterpart of the nonmonotonic preferential system (see [2, 19, 10]) In other words, the logic for # contains besides classical propositional logic, the following axioms A...
