Positive solutions for concave-convex type problems for the one-dimensional $ϕ$ -Laplacian

Uriel Kaufmann, Leandro Milne

Let $Ω = (a, b) \subset R$ , $0 \leq m, n \in L^{1} (Ω)$ , $λ, μ > 0$ be real parameters, and $ϕ : R \to R$ be an odd increasing homeomorphism. In this paper we co…

Positive solutions for nonlinear problems involving the one-dimensional ϕ-Laplacian

Uriel Kaufmann, Leandro Milne

Let $Ω := (a, b) \subset R$ , $m \in L^{1} (Ω)$ and $λ > 0$ be a real parameter. Let $L$ be the differential operator given by $\mathcal{L}u:=-ϕ\…

One-dimensional singular problems involving the p-Laplacian and nonlinearities indefinite in sign

Uriel Kaufmann, Iván Medri

Let $Ω$ be a bounded open interval, let $p > 1$ and $γ > 0$ , and let $m : Ω \to R$ be a function that may change sign in $Ω$ . In this article we study the existence and no…

Strictly positive solutions for one-dimensional nonlinear elliptic problems

Uriel Kaufmann, Ivan Medri

We study existence and nonexistence of strictly positive solutions for the elliptic problems of the form $Lu = m (x) u^{p}$ in a bounded open interval, with zero boundary…
