A local saddle point theorem and an application to a nonlocal PDE
Department or Administrative Unit
We prove a local saddle point theorem that can be viewed as a generalization of the saddle point theorem of Rabinowitz. A difficulty to overcome is that there isn't any linking. We then apply the theorem to show the existence of solutions of a nonlocal partial differential equations.
