Giacomo Bonanno, Temporal belief revision rationalized by plausibility orderings

Abstract.

Within the class of structures introduced in [G. Bonanno, Axiomatic characterization of the AGM theory of belief revision in a temporal logic, Artificial Intelligence, 171 (2007), 144-160] we consider the
subclass satisfying the property that, for every state-instant pair (omega,t), there is an ordering of the set of states that rationalizes the revised beliefs at every (omega,t') where t' is an immediate successor of t.
We characterize this class both semantically and syntactically.

 Giacomo Bonanno, Belief revision in a temporal framework.
Abstract.
We study a branching-time temporal logic of belief revision where the interaction of belief and information is modeled explicitly. The logic is based on three modal operators: a belief operator, an information operator and a next-time operator. We consider three logics of increasing strength. The first captures the most basic notion of minimal belief revision. The second characterizes the qualitative content of Bayes' rule. The third is the logic proposed in Bonanno, Artificial Intelligence, 2007, where some aspects of its relationship with the AGM theory of belief revision were investigated. We further explore the relationship to AGM with the help of semantic structures that have been used in the rational choice literature. Further strengthening of the logic are also investigated..

 Giacomo Bonanno, A sound and complete temporal logic for belief revision.
Abstract.
Branching-time temporal logic offers a natural setting for a theory of belief change. We propose a temporal logic that, besides the next-time operator, contains a belief operator and an information operator. It is shown that this logic is sound and complete with respect to the class of branching-time frames augmented, for each instant t, with a set of states and two binary relations on it, representing beliefs and information, respectively.
