报告题目:Concentration of nodal solutions for semiclassical NLS

报告摘要:We discuss the existence of localized sign-changing solutions for the semiclassical nonlinear Schrödinger equation. When $V$ has a local minimum point $P$, as $\epsilon \to 0$, we construct an infinite sequence of localized sign-changing solutions clustered at $P$ and these solutions are of higher topological type. Our method is rather robust without using any non-degeneracy condition.
