Remarks on Potential Mean Field Games

Mean field games were introduced about 20 years ago to model the limit of N-player differential games as N goes to infinity. There are many applications to economics, finance, social sciences and biology. In many interesting cases the Nash equilibrium turns out to be a critical point for a functional, called the potential, in which case the game itself is called potential. In this case I will present several mathematical results on potential mean field games, which are directly connected to the theory of optimal control of PDE.

Polyharmonic Maass forms and Hecke series for real quadratic fields

We study polyharmonic Maass forms and show that they are related to ray class extensions of real quadratic fields. In particular, we generalize work of Lagarias and Rhoades to give a basis for the space of polyharmonic Maass forms for $\Gamma(N)$. Modifying an argument of Hecke, we show that twisted traces of cycle integrals of certain depth 2 polyharmonic Maass forms are leading coefficients of Hecke $L$-series of real quadratic fields. This is ongoing joint work with Gene Kopp.
