Optimal regularity for the pseudo infinity laplacian
ESAIM: Control, Optimisation and Calculus of Variations, Tome 13 (2007) no. 2, pp. 294-304.

In this paper we find the optimal regularity for viscosity solutions of the pseudo infinity laplacian. We prove that the solutions are locally Lipschitz and show an example that proves that this result is optimal. We also show existence and uniqueness for the Dirichlet problem.
