Abstract

The AGM theory of belief contraction is extended to multiple contraction, i.e. to contraction by a set of sentences rather than by a single sentence. There are two major variants: In package contraction all the sentences must be removed from the belief set, whereas in choice contraction it is sufficient that at least one of them is removed. Constructions of both types of multiple contraction are offered and axiomatically characterized. Neither package nor choice contraction can in general be reduced to contractions by single sentences; in the finite case choice contraction allows for reduction.
