Theory Contraction and Base Contraction Unified

Part of the Springer Graduate Texts in Philosophy book series (SGTP, volume 1)

Abstract

One way to construct a contraction operator for a theory (belief set) is to assign to it a base (belief base) and an operator of partial meet contraction for that base. Axiomatic characterizations are given of the theory contractions that are generated in this way by (various types of) partial meet base contractions.
