Private Revision in a Multi-Agent Setting (Extended Abstract)

AGM belief change aims at modeling the evolution of an agent’s beliefs about her environment. In many applications though, a set of agents sharing the same environment must be considered. For such scenarios, beliefs about other agents’ beliefs must be taken into account. In this work, we study the private revision issue in a multi-agent setting represented by a KD45n model. More precisely, we investigate the changes induced by a new piece of objective information made available to one agent in the set. We point out an adaptation of AGM revision postulates to this setting, and present some specific revision operators.
