一类大参数Robin问题的渐近特征值估计

Asymptotic eigenvalue estimates for a Robin problem with a large parameter

Pavel Exner, Alexander Minakov, Leonid Parnovski

摘要:

研究了具有光滑边界和大参数边界条件的有界平面区域上拉普拉斯算子的Robin问题。我们证明了负特征值的双边三项渐近估计。此外,通过改进上界,我们得到了关于耦合常数和边界曲率最大值的两项渐近性。

英文摘要:

Robin problem for the Laplacian in a bounded planar domain with a smooth boundary and a large parameter in the boundary condition is considered. We prove a two-sided three-term asymptotic estimate for the negative eigenvalues. Furthermore, improving the upper bound we get a two term asymptotics in terms of the coupling constant and the maximum of the boundary curvature.
