Positive solutions to sublinear elliptic problems
Zeineb Ghardallou · Colloquium Mathematicum · 2018
Let $L$ be a second order symmetric elliptic operator with smooth coefficients defined on a domain $\Omega $ in $\mathbb{R}^d $, $d\geq3$, such that $L1\leq 0$. We study existence and properties of continuous solutions to the problem \begin{equation}\labe
