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

Uriel Kaufmann, Leandro Milne

Let $\Omega =(a,b)\subset \mathbb{R}$, $0\le m,n\in L^1(\Omega )$, $\lambda ,\mu >0$ be real parameters, and $\varphi :\mathbb{R}\to \mathbb{R}$ be an odd increasing homeomorphism. In this paper we co…
