Towards Dynamic Distributed Knowledge

Abstract

We propose a novel notion of distributed knowledge called dynamic distributed knowledge that corresponds to what a group of agents know after they share their knowledge. Its interpretation in Kripke models therefore combines static (modal accessibility) with dynamic (update) aspects. In prior work the static and dynamic aspects were also investigated, but separately, where the latter was called resolution. Unlike the usual distributed knowledge, in this work called static distributed knowledge, if a group of agents has dynamic distributed knowledge of a proposition, then it has dynamic distributed knowledge that the proposition is common knowledge. We report on its expressivity, axiomatization, and bisimulation characterization.
