The junior seminar aims at gathering PhD students and post-docs whose research topics deal with game theory in a broad sense. During the seminar, the participants may present their works, advanced or in progress, to their peers. They may also present articles they believe are interesting (in a journal club fashion). They can be theoretical economists, mathematicians, and computer scientists. The seminar will take place around every two weeks on Mondays, 10am, before the senior game theory seminar. Participants who would like to give a talk are most welcome and are encouraged to contact the organizers. If you would like to join the seminar mailing list, please do not hesitate to contact the organizers as well.
Next Seminar is on June 29, 2026 (room Maryam Mirzakhani):
Ivan Novikov will present the work:
Title: Zero-Sum Stochastic Games with Frequent Actions and Vanishing Discount Factors
Abstract: In this talk, we discuss zero-sum stochastic games, in which two players choose actions at each stage, with Player 1 trying to maximize and Player 2 trying to minimize the discounted payoff. We consider what happens when we have simultaneously:
1) the players are patient (i.e. the discount factor vanishes), and
2) the players choose actions frequently.
We examine some known facts on the matter, as well as explore some open questions. The talk is based on [1], [2] and [3].
