Abstract:

In this paper we prove $C^{1,\alpha}$-regularity (near flat points) of the free boundary $\partial\{u>0\}\cap\Omega$ in the Alt-Caffarelli type minimum problem for the $p$-Laplace operator: $$ J(u)=\int\Omega\left(
\nabla u
p + \lambdap\chi{\{u>0\}}\right)dx\rightarrow \min\qquad (1<p<\infty.) $$
