报 告 人:彭双阶,华中师范大学教授,博导,副校长
报告摘要:This talk is related to a singularly perturbed nonlinear Schrodinger equation. We obtain a more accurate location for the concentrated points,the existence and the local uniqueness for positive peak solutions when the potential V(x) possesses non-isolated critical points by using the modified finite dimensional reduction method based on local Pohozaev identities Moreover, for several special potentials,with its critical point set being a lower dimensional ellipsoid, or a part of hyperboloid of one sheet or two sheets, we obtain the number and symmetry of k-peak solutions by using local uniqueness of concentrated solutions. Here the main difficulty comes from the different degenerate rate along different directions at the critical points of V(x).
