我们考虑一个具有斥力的平稳非线性薛定谔方程 一维空间中的δ函数杂质。这个方程承认一个唯一的 正解且该解是偶数。我们证明它是一个最小化器 $H^1(\R, \C)$ 偶函数子空间上的相关能量, 但不是所有$H^1(\R, \C)$,并研究其轨道稳定性。
We consider a stationary nonlinear Schroodinger equation with a repulsive delta-function impurity in one space dimension. This equation admits a unique positive solution and this solution is even. We prove that it is a minimizer of the associated energy on the subspace of even functions of $H^1(\R, \C)$, but not on all $H^1(\R, \C)$, and study its orbital stability.
