Steklov问题的热不变量

Heat invariants of the Steklov problem

Iosif Polterovich, David A. Sher

摘要:

研究了带边界的黎曼流形上Steklov本征值问题的热迹渐近性。特别是,我们描述的Steklov热不变量的结构和计算的前几个明确的标量和中曲率。这是通过将Seeley演算应用于Dirichlet-to-Neumann算子来完成的,其谱与Steklov特征值一致。作为应用,证明了在所有具有光滑连通边界的欧几里得整环中,一个三维球是由它的Steklov谱唯一定义的.

英文摘要:

We study the heat trace asymptotics associated with the Steklov eigenvalue problem on a Riemannian manifold with boundary. In particular, we describe the structure of the Steklov heat invariants and compute the first few of them explicitly in terms of the scalar and mean curvatures. This is done by applying the Seeley calculus to the Dirichlet-to-Neumann operator, whose spectrum coincides with the Steklov eigenvalues. As an application, it is proved that a three--dimensional ball is uniquely defined by its Steklov spectrum among all Euclidean domains with smooth connected boundary.
