Link Download full text Abstract We give necessary and sufficient conditions for functions to be solutions to overdetermined problems for the equation $- Delta_ infty u=1$ in a bounded domain of $R^n$. To this end, we introduce a P-function for the study of the Dirichlet problem and we make use of its properties.
