On partially free boundary solutions for elliptic problems with non-Lipschitz nonlinearities
Applied Mathematics Letters, 95, (2019) 23-28 We show that the elliptic equation with a non-Lipschitz right-hand side, $-\Delta u = \lambda |u|^{\beta-1}u - |u|^{\alpha-1}u$ with $\lambda>0$ and $0<\alpha<\beta<1$, considered on a smooth star-shaped domain $\Omega$ subject to zero Dirich...

| Summary: | Applied Mathematics Letters, 95, (2019) 23-28 We show that the elliptic equation with a non-Lipschitz right-hand side,
$-\Delta u = \lambda |u|^{\beta-1}u - |u|^{\alpha-1}u$ with $\lambda>0$ and
$0<\alpha<\beta<1$, considered on a smooth star-shaped domain $\Omega$ subject
to zero Dirichlet boundary conditions, might possess a nonnegative ground state
solution which violates Hopf's maximum principle only on a nonempty subset
$\Gamma$ of the boundary $\partial\Omega$ such that $\Gamma \neq
\partial\Omega$. |
