nonlinear elliptic问题位势鞍点周围的正变号簇

Positive and sign-changing clusters around saddle points of the potential for nonlinear elliptic problems

Teresa D'Aprile, David Ruiz

摘要:

研究了一类定常非线性Schroedinger方程正的变号多峰解的存在性。这里假设$V$上没有对称性。已知该方程具有正的多峰解,其中所有峰都接近电势的局部极大值。证明了在极小值的情况下,存在正负尖峰交替的解。本文的目的是证明在外部势的非退化鞍点附近正的和变号的多峰解的存在性。

英文摘要:

We study the existence of positive and sign-changing multipeak solutions for the stationary Nonlinear Schroedinger Equation. Here no symmetry on $V$ is assumed. It is known that this equation has positive multipeak solutions with all peaks approaching a local maximum of the potential. It is also proved that solutions alternating positive and negative spikes exist in the case of a minima. The aim of this paper is to show the existence of both positive and sign-changing multipeak solutions around a nondegenerate saddle point of the external potential.
