Dirichlet Problems with an Indefinite and Unbounded Potential and Concave-Convex Nonlinearities
We consider a parametric semilinear Dirichlet problem with an unbounded and indefinite potential. In the reaction we have the competing effects of a sublinear (concave) term and of a superlinear (convex) term. Using variational methods coupled with suitable truncation techniques, we prove two multip...
