论文名称:A free boundary problem for p-Laplacian in the plane
发表刊物:J. Math. Anal. Appl., 380(2011), 10-16.
摘要:Abstract:
We consider the following free boundary problem in an unbounded
domain $Omega$ in two dimensions: $Delta_p u=0$ in $Omega$,
$u=0, frac{partial{u}}{partial n}=g_0$ on $J_0$, $u=1,
frac{partial{u}}{partial n}=g_1$ on $J_1$, where
$partialOmega=J_0cup J_1$. We prove that if $0<u<1$ in $Omega$,
$J_i$ is the graph of a function in $C^{1,alpha}_{loc}({
l})$ and
$g_i$ is a constant for each $i=0,1$, then the free boundary
$partialOmega$ must be two parallel straight lines and the
solution $u$ must be a linear function. The proof is based on
maximum principle.
