Abstract

The stationary Schrödinger equation is studied in a domain bounded by two confocal ellipses and in its coverings. The order of dependence of the Laplace operator eigenvalues on sufficiently small distance between the foci is obtained. Coefficients of the power series expansion of said eigenvalues are calculated up to and including the square of half the focal distance.

椭圆环覆盖中的薛定谔算子谱

摘要研究了在由两个共焦椭圆及其覆盖物所限定的域中的静止薛定谔方程。得出了拉普拉斯算子特征值对焦点之间足够小的距离的依赖阶次。计算了上述特征值的幂级数展开系数，其中包括半焦距的平方。
