The LIRa seminar is a series of talks organized by the Amsterdam Dynamics Group, focusing on the logical, philosophical and computational aspects of agency, rational interaction and social-informational dynamics. The seminar covers research topics lying at the interface of Logic with Game Theory, Decision Theory, Learning Theory, Formal Epistemology, Social Choice Theory, Computer Science, Philosophy of Science or Philosophy of Language. Core areas of interest are Modal Logic approaches to interaction, as well as other approaches, e.g. game semantics, dynamic semantics for natural language, (co)algebraic approaches, or (in)dependence-friendly logics.
