基于上三角紧算子的透射本征值的离散性

Discreteness of Transmission Eigenvalues via Upper Triangular Compact Operators

John Sylvester

摘要:

我们证明了内部传输特征值是离散的,通过证明内部传输算子具有上三角紧预解式,并且这些算子的谱共享具有紧预解式的算子的许多性质。特别地,谱是离散的,并且广义本征空间是有限维的。我们的主要假设是一个非线性条件的对比度,必须保持只有在附近的边界。

英文摘要:

We show that the interior transmission eigenvalues are discrete by proving that the interior transmission operator has upper triangular compact resolvent, and that the spectrum of these operators share many of the properties of operators with compact resolvent. In particular, the spectrum is discrete and the generalized eigenspaces are finite dimensional. Our main hypothesis is a coercivity condition on the contrast that must hold only in a neighborhood of the boundary.
