Index and Robustness of Mixed Equilibria: An Algebraic Approach
Lucas Pahl
We present a new method for computation of the index of completely mixed equilibria in finite games, based on the work of Eisenbud et al.(1977). We apply this method to solving two…

Robust Equilibria in Generic Extensive form Games
Lucas Pahl, Carlos Pimienta
We prove the 2-player, generic extensive-form case of the conjecture of Govindan and Wilson (1997a,b) and Hauk and Hurkens (2002) stating that an equilibrium component is essential…

O'Neill's Theorem for Games
Srihari Govindan, Rida Laraki, Lucas Pahl
We present an analog of O'Neill's Theorem (Theorem 5.2 in [17]) for finite games, which reveals some of the structure of equilibria under payoff perturbations in finite games.
