A bifurcation-type theorem for the positive solutions of a nonlinear Neumann problem with concave and convex terms
Abstract
We consider a nonlinear elliptic Neumann problem driven by the p-Laplacian with a reaction that involves the combined effects of a “concave” and of a “convex” terms. The convex term (p-superlinear term) need not satisfy the Ambrosetti-Rabinowitz condition. Employing variational methods based on the critical point theory together with truncation techniques, we prove a bifurcation type theorem for the equation.The authors retain all rights to the original work without any restrictions.
