Eigenvalue bounds for non-self-adjoint Schrödinger operators with non-trapping metrics

Colin Guillarmou, Andrew Hassell, Katya Krupchyk

摘要:

本文研究了$n\ge 3$维非陷获渐近锥流形上的非自伴薛定谔算子的特征值.具体而言,我们关注以下两种类型的估计。第一个是关于具有复势的薛定谔算子的单个本征值的Keller型界,它是关于复势的$L^p$ -范数的;第二个是关于复势的本征值的幂和的Lieb-Thirring型界,它是关于复势的$L^p$ -范数的。我们将Frank(2011),Frank-Sabin(2017)和Frank-Simon(2017)关于Keller和Lieb-Thirring型界的结果从欧几里得空间的情况扩展到非捕获渐近圆锥流形的情况。特别是,我们的结果是有效的运营商$Δ_g+V$ $\mathbb{R}^n$与$g$是一个非捕获compensable支持(或适当的短范围)的欧几里德度量和$V\in L^p$复杂值的扰动。

英文摘要:

We study eigenvalues of non-self-adjoint Schrödinger operators on non-trapping asymptotically conic manifolds of dimension $n\ge 3$. Specifically, we are concerned with the following two types of estimates. The first one deals with Keller type bounds on individual eigenvalues of the Schrödinger operator with a complex potential in terms of the $L^p$-norm of the potential, while the second one is a Lieb-Thirring type bound controlling sums of powers of eigenvalues in terms of the $L^p$-norm of the potential. We extend the results of Frank (2011), Frank-Sabin (2017), and Frank-Simon (2017) on the Keller and Lieb-Thirring type bounds from the case of Euclidean spaces to that of non-trapping asymptotically conic manifolds. In particular, our results are valid for the operator $Δ_g+V$ on $\mathbb{R}^n$ with $g$ being a non-trapping compactly supported (or suitably short range) perturbation of the Euclidean metric and $V\in L^p$ complex valued.
