混合流形上的预解式展开

Resolvent expansions on hybrid manifolds

Konstantin Pankrashkin, Svetlana Roganova, Nader Yeganefar

摘要:

我们研究Laplace型算子的混合流形,即在配置组成的封闭的二维流形和一维段。这样的算子可以通过在每个分量上使用Laplace-Beltrami算子来构造,在胶合点处具有一些边界条件。得到了预解式二次幂迹的大谱参数展开式。讨论了逆谱理论的一些问题。

英文摘要:

We study Laplace-type operators on hybrid manifolds, i.e. on configurations consisting of closed two-dimensional manifolds and one-dimensional segments. Such an operator can be constructed by using the Laplace-Beltrami operators on each component with some boundary conditions at the points of gluing. The large spectral parameter expansion of the trace of the second power of the resolvent is obtained. Some questions of the inverse spectral theory are adressed.
