A generalization of the Hopf–Cole transformation for stationary Mean-Field Games systems
[Une généralisation de la transformation de Hopf–Cole pour des systèmes de jeux à champ moyen stationnaires]
Comptes Rendus. Mathématique, Volume 353 (2015) no. 9, pp. 807-811.

On propose dans cette Note une transformation qui découple les systèmes de jeux à champ moyen stationnaires pour des hamiltoniens superlinéaires de la forme |p|r,r>1, et qui transforme l'équation de Hamilton–Jacobi–Bellman en une équation quasi linéaire introduisant le r-laplacien. Une telle transformaton nécessite une hypothèse sur la solution : cette hypothèse est satisfaite, par exemple, dans le cas unidimensionnel ou dans le cas où la solution est radiale.

In this note we propose a transformation that decouples stationary Mean-Field Games systems with superlinear Hamiltonians of the form |p|r, r>1, and turns the Hamilton–Jacobi–Bellman equation into a quasi-linear equation involving the r-Laplace operator. Such a transformation requires an assumption on solutions to the system, which is satisfied for example in space dimension one or if solutions are radial.
