证明了非自伴Jacobi算子特征值上的lieb - thirring型界,其强度与Hundertmark和Simon先前证明的自伴Jacobi算子相同。我们使用了一种基于算子行列式和复函数理论的方法,扩展和改进了Borichev, Golinskii和Kupin的早期工作。
We prove Lieb-Thirring-type bounds on eigenvalues of non-selfadjoint Jacobi operators, which are nearly as strong as those proven previously for the case of selfadjoint operators by Hundertmark and Simon. We use a method based on determinants of operators and on complex function theory, extending and sharpening earlier work of Borichev, Golinskii and Kupin.
