Perfect information games have become an important analytical tool in a number of different disciplines, including descriptive set theory, logic, computer science, and economics. This short course offers an introduction to some mathematical aspects of the theory of perfect information games. We start with a discussion of determinacy, centering around Martin’s landmark result on determinacy of Borel games. We then proceed to introduce n-player perfect information games. In this setup, we will discuss the existence of epsilon-Nash equilibrium. We next introduce sub-game perfect epsilon-equilibrium and its variations, and review several sufficient topological conditions for its existence. In the final lecture of the course, we turn our attention to games with simultaneous moves, and review Blackwell determinacy and quitting games.
