Abstract:  We discuss the existence of localized nodal solutions for the semiclassical nonlinear Schrödinger equation with the potential V assumed to have a local minimum point P. As , we construct an infinite sequence of localized nodal solutions clustered at P these solutions are of higher topological type in the sense that they are obtained from a minimax characterization of higher dimensional symmetric linking structure. Our method is rather robust without using any non-degeneracy condition.
