Public Announcements and Belief Expansion

In this paper we study the relation between two approaches to information change: Dynamic Epistemic Logic and Belief Revision. One of the main differences between these approaches is that higher-order information plays an important role in the field of Dynamic Epistemic Logic, whereas it does not feature in Belief Revision. In this paper we study to which extent public announcements (a particular kind of information change studied in Dynamic Epistemic Logic) can be viewed as a belief expansion (a particular kind of information change studied in Belief Revision).
