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 or computer scientists.
The seminar takes place around every two weeks on Mondays before the senior game theory seminar, at 10am.
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 Monday, September 28th, at the Institute Henri Poincaré (IHP) (room Maryam Mirzakhani 201), 11 rue Pierre et Marie Curie, Paris 75005, at 10:00 to 11:00.
Anne Reulke will come to present her work, whose title and summary are:
Title : Equilibrium and Infeasibility : A new solution concept for games
Abstract : Addressing infeasibility in non-cooperative games has become an important topic, as many problems across different applications face this issue. We propose a new solution concept for generalized games with possibly infeasible individual constraints. A solution is defined as the limit of a sequence of generalized Nash equilibria induced by games with penalty terms relaxing the individual constraints. Existence is established for a broad range of games and we provide conditions allowing to characterize a ψ-penalized solution as a strategy profile maximizing every player's utility over all her penalty minimizing strategies. A variation of Divide-the-Dollar serves as an illustrative example. We further establish the compatibility with the GNE and the solution to the Nash bargaining.
