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. 

      Speaker Introduction王志强教授,在1980年代先后在吉林大学、中科院数学所、北京大学学习,在张恭庆院士指导下获博士学位后,到著名的美国柯朗研究所从事研究工作。他将Morse理论应用于椭圆边值问题,获得超线性椭圆方程的三个非平凡解,引起学界很大的震动,并导致90年代以来Morse理论及其应用方面的热潮。自90年代以来他致力于各种非线性Schrodinger方程和Schrodinger方程组等不失去紧性的变分问题的研究,取得了很多重要的研究成果,是国际著名的非线性分析和偏微分方程专家。
