Filtered belief revision and generalized choice structures

Bonanno, Giacomo - 2020

generalized notion of) choice structure in terms of belief revision by adding: (1) the possibility that an item of ''information …'' might be discarded as not credible (thus dropping the AGM success axiom) and (2) the possibility that an item of information …, while not accepted as fully credible, may still be ''taken seriously'' (we call such items of information ''allowable''). We …

A Kripke-Stalnaker-Lewis semantics for AGM belief revision

Bonanno, Giacomo - 2023

We provide a new characterization of AGM belief revision in terms of a Kripke-Stalnaker-Lewis semantics. We consider pointed frames consisting of a set of states, a distinguished state interpreted as the actual state, a Kripke belief relation and a Stalnaker-Lewis selection function. Adding a...

A Kripke-Lewis semantics for belief update and belief revision

Bonanno, Giacomo - 2023

We provide a new characterization of both belief update and belief revision in terms of a Kripke-Lewis semantics. We consider frames consisting of a set of states, a Kripke belief relation and a Lewis selection function. Adding a valuation to a frame yields a model. Given a model and a state, we...

Belief change in branching time: AGM-consistency and iterated revision

Bonanno, Giacomo - 2010

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...
