摘    要:利用Lyapunov-Schmidt方法证明了带有一阶导数项和(V)α势函数的非线性Schrodinger方程半经典孤波解的存在性及其集中性质. 具体地讲,当相当于Planck常数的奇摄动参数趋于零时,证明了该非线性Schrodinger方程的孤波解存在并且这些解在其势函数的非退化临界点处集中. 研究的是椭圆型方程的奇摄动问题,方程带有一阶导数项是本文特征之一.

关 键 词:非线性Schrodinger方程    Lyapunov-Schmidt方法    压缩映射原理

Abstract:The authors study the existence and concentration of semi-classical solitary waves for a class of nonlinear Schr¨odinger equations with first order derivative terms and (V ) potentials. Precisely, as the singularly perturbed parameter which corresponds to Planck constant approches to zero, the solitary waves of these nonlinear Schr¨odinger equations concentrate at the non-degenerate critical points of potentials. The authors concern singular perturbation of semilinear elliptic equations with first order derivative terms and this is also a new feature of the paper.
Keywords:Nonlinear Schrodinger equation  Lyapunov-Schmidt method  Contraction mapping principle
