Title: Compositional Game Theory.

Abstract. Open games are a foundation of non-cooperative game theory that is strongly compositional: all games are built from small pieces using sequential and parallel composition operators. They also come for free with an intuitive but formal graphical language that allows visualising the information flow inside a game. I will focus on the foundations, which involves a careful analysis of how observable and counterfactual information interact in a game. Time permitting I’ll briefly discuss a linguistic application, building language-games recursively on a categorial grammar (work in progress with Martha Lewis). This talk necessarily involves some category theory, but I’ll try to be as gentle as possible.
