Diversity of Agents and their Interaction
Fenrong Liu

Abstract:
Diversity of agents occurs naturally in epistemic logic, and dynamic
logics of information update and belief revision. We provide a
systematic discussion of different sources of diversity, such as
introspection ability, powers of observation, memory capacity, and
revision policies, and we show how these can be encoded in dynamic
epistemic logics allowing for individual variation among agents. Next,
we explore the interaction of diverse agents by looking at some
concrete scenarios of communication and learning, and we propose a
logical methodology to deal with these as well. We conclude with some
further questions on the logic of diversity and interaction.
