Subsolutions: A journey from positone to infinite semipositone problems
We discuss the existence of positive solutions to $-Delta u=lambda f(u)$ in $Omega$, with $u=0$ on the boundary, where $lambda$ is a positive parameter, $Omega$ is a bounded domain with smooth boundary $Delta $ is the Laplacian operator, and $f:(0,infty)o R$ is a continuous function. We first d...
