摘要:

该文利用约束变分的方法, 研究了三维空间中一类带有非齐次项的薛定谔方程存在基态解的最佳参数范围, 并讨论了基态解随参数变化的质量集中行为.

关键词: 约束变分, 基态解, 能量估计, 集中行为

Abstract:

In this paper, we employ the constrained variational method to investigate the optimal parameter range for the existence and non-existence of ground states to a class of Schrödinger equations with inhomogeneous terms in three-dimensional space, and discusses the mass concentration behavior of the ground states with respect to the variation of the parameter.

Key words: constrained variation, ground states, energy estimation, concentration behavior
