Belief Change in Branching Time: AGM-consistency and Iterated Revision
We study belief change in the branching-time structures introduced in [4]. First, we identify a property of branching-time frames that is equivalent to AGM-consistency, which is defined as follows. A frame is AGM-consistent if the partial belief revision function associated with an arbitrary state-instant pair and an arbitrary model based on that frame can be extended to a full belief revision ...
متن کاملA foundationalist view of the AGM theory of belief change
We describe an alternative interpretation of the AGM postulates for belief change (Alchourrón et al., 1985; Gärdenfors, 1988) in a foundational framework of epistemic states suggested by Bochman (1997). Though foundational contractions constitute a new kind of belief contractions, incompatible with AGM postulates, a broad class of preferential AGM contractions is shown to be revisionequivalent ...
متن کاملBayesian updating rules and AGM belief revision
We interpret the problem of updating beliefs as a choice problem (selecting a posterior from a set of admissible posteriors) with a reference point (prior). We use AGM belief revision to define the support of admissible posteriors after observing zero probability events and investigate two classes of updating rules for probabilities : 1) ”minimum distance” updating rules which select the poster...

متن کاملAGM Belief Revision in Monotone Modal Logics
Classical modal logics, based on the neighborhood semantics of Scott and Montague, provide a generalization of the familiar normal systems based on Kripke semantics. This paper defines AGM revision operators on several first-order monotonic modal correspondents, where each first-order correspondence language is defined by Marc Pauly’s version of the van Benthem characterization theorem for mono...
