Multiple solutions for some elliptic equations with a nonlinearity concave at the origin

Alternate approximation of concave cost functions for process design and supply chain optimization problems
(Elsevier, 2014-01)
This short note presents an alternate approximation of concave cost functions used to reflect economies of scale in process design and supply chain optimization problems. To approximate the original concave function, we ...
The Nehari manifold for nonlocal elliptic operators involving concave-convex nonlinearities
(SPRINGER BASEL AG, 2015)
In this paper, we study the multiplicity of solutions to equations driven by a nonlocal integro-differential operator with homogeneous Dirichlet boundary conditions. In particular, using fibering maps and Nehari manifold, ...
Local superlinearity and sublinearity for indefinite semilinear elliptic problems

Existence of orthogonal geodesic chords on Riemannian manifolds with concave boundary and homeomorphic to the N-dimensional disk
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
In this paper we give a proof of the existence of an orthogonal geodesic chord on a Riemannian manifold homeomorphic to a closed disk and with concave boundary. This kind of study is motivated by the link (proved in Giambo ...
A limiting problem for local/non-local p-Laplacians with concave–convex nonlinearities
(Birkhauser Verlag Ag, 2020-12)
In this manuscript, we deal with an equation involving a combination of quasi-linear elliptic operators of local and non-local nature with p-structure, and concave?convex nonlinearities. The prototypical model is given by ...
