چکیده
We propose a very general syntactical notion of epistemic state and a compact axiomatization for iterated revision when the new information is an epistemic state. We set representation theorems and give two semantical representations of operators: by polynomials and by weighted belief bases. These representations will result to be equivalent.

Iterated Revision by Epistemic States: Axioms, Semantics and Syntax
We propose a very general syntactical notion of epistemic state and a compact axiomatization for iterated revision when the new information is an epistemic state. We set representation theorems and give two semantical representations of operators: by polynomials and by weighted belief bases. These representations will result to be equivalent.
متن کاملA Conditional Logic for Iterated Belief Revision
In this paper we propose a conditional logic IBC to represent iterated belief revision. We define an iterated belief revision system by strengthening the postulates proposed by Darwiche and Pearl [3]. First, following the line of Darwiche and Pearl, we modify AGM postulates to make belief revision a function of epistemic states rather than of belief sets. Then we propose a set of postulates for...
متن کاملThree Scenarios for the Revision of Epistemic States
This position paper discusses the difficulty of interpreting iterated belief revision in the scope of the existing literature. Axioms of iterated belief revision are often presented as extensions of the AGM axioms, upon receiving a sequence of inputs. More recent inputs are assumed to have priority over less recent ones. We argue that this view of iterated revision is at odds with the claim, ma...
متن کاملIterated revision and the axiom of recovery: a unified treatment via epistemic states
The axiom of recovery, while capturing a central intuition regarding belief change, has been the source of much controversy. We argue briefly against putative counterexamples to the axiom— while agreeing that some of their insight deserves to be preserved— and present additional recovery-like axioms in a framework that uses epistemic states, which encode preferences, as the object of revisions....
