证明了带边界紧致曲面上Steklov特征值的重数的两个显式界。其中一个界限仅取决于曲面的亏格和特征值的指数$k,而另一个界限还取决于边界分量的数目。我们还证明了在任何给定的有边界的光滑黎曼曲面上,Steklov本征值的重数在$k中一致有界。
We prove two explicit bounds for the multiplicities of Steklov eigenvalues $\sigma_k$ on compact surfaces with boundary. One of the bounds depends only on the genus of a surface and the index $k$ of an eigenvalue, while the other depends as well on the number of boundary components. We also show that on any given smooth Riemannian surface with boundary, the multiplicities of Steklov eigenvalues $\sigma_k$ are uniformly bounded in $k$.
