Perspectives on belief and change

Abstract : In this thesis, we propose logical models for belief representation and belief change in a multi-agent setting, stressing the importance of choosing a particular modeling point of view. In that respect, we distinguish two approaches: the external approach, where the modeler is somebody external to the situation; the internal approach, where the modeler is one of the agents. We propose an internal version of dynamic epistemic logic (with event models) which allows us to generalize easily AGM belief revision theory to the multi-agent case. Afterwards, we model the complex logical dynamics underlying the interpretation of events by adding probabilities and infinitesimals. Finally we propose an alternative without using event models by introducing instead a converse event operator.
