Existence of solutions to p-Laplace equations with logarithmic nonlinearity

Jing Mo, Zuodong Yang

Abstract:
This article concerns the the nonlinear elliptic equation
$$ -\hbox{div}(|\nabla u|^{p-2}\nabla u) =\log u^{p-1}+\lambda f(x,u) $$
in a bounded domain $\Omega \subset \mathbb{R}^{N}$ with $N\geq 1$ and $u=0$ on $\partial\Omega$. By means of a double perturbation argument, we obtain a nonnegative solution.
