一类非紧支势的透射本征值

Transmission Eigenvalues for a Class of Non-Compactly Supported Potentials

Esa V. Vesalainen

摘要:

设$Ω\subseteq\mathbb R^n$是一个非空的开集,其Sobolev嵌入$H_0^2(Ω)\longrightarrow L^2(Ω)$是紧的,$V\in L^\infty(Ω)$是一个只取正实值的势函数,且对某些$α\in\left]3,\infty\right[$满足渐近性$V(\cdot)\asymp\left\langle\cdot\right\rangle^{-α}$.我们建立了离散的薛定谔和亥姆霍兹散射与这些潜在的一组真正的传输本征值。

英文摘要:

Let $Ω\subseteq\mathbb R^n$ be a non-empty open set for which the Sobolev embedding $H_0^2(Ω)\longrightarrow L^2(Ω)$ is compact, and let $V\in L^\infty(Ω)$ be a potential taking only positive real values and satisfying the asymptotics $V(\cdot)\asymp\left\langle\cdot\right\rangle^{-α}$ for some $α\in\left]3,\infty\right[$. We establish the discreteness of the set of real transmission eigenvalues for both Schrödinger and Helmholtz scattering with these potentials.
