Abstract

We address the issue of belief revision in a multi-agent setting. We represent agents' beliefs in a semantic manner, through a Kripke structure, and model a communication process by which agents communicate their beliefs to one another. We define a revision rule that can be applied even when agents have contradictory beliefs. We study its properties and show that agents need not agree after communicating their beliefs. We finally address the dynamics of revision and show that the order of communication may affect the resulting belief structure.
