Global multiplicity results in a Moore-Nehari type problem with a spectral parameter

Julián López-Gómez, Eduardo Muñoz-Hernández, Fabio Zanolin

This paper analyzes the structure of the set of positive solutions of a Moore-Nehari type problem, where $a \equiv a_{h}$ is a piece-wise constant function defined for some $h\in (0,1…

Non-negative solutions of a sublinear elliptic problem

Julián López-Gómez, Paul H. Rabinowitz, Fabio Zanolin

In this paper the existence of solutions, $(λ, u)$ , of the problem $- Δ u = λ u - a (x) ∣ u ∣^{p - 1} u in Ω, u = 0 on \partial Ω,$ is explored for $0 < p < 1$ …
