In this presentation,a variational free boundary problem of phase transition for the p-Laplace equation will be introduced,for 1 < p < ∞.The existence of a minimizer,the free boundary condition,and non-degeneracy of the minimizer will be proved.This project follows in line with Alt,Caffarelli,and Friedmans work on a similar free boundary problem for the Laplacian.Nevertheless,in the current situation,a counterpart of a monotonicity formula which plays a pivotal role in the latter is absent.Moreover,if one sends p to infinity,one can prove a uniform limit of the minimizers of the variational problem for the p-Laplacian satisfies a free boundary problem for the infinity Laplacian,albeit not in the variational form any more.
