秩一扰动预解式的注记

Notes on Rank-One Perturbed Resolvent

Sergej A. Choroszavin

摘要:

本文是对S.R. Foguel {Banach空间中的\it有限维扰动}。主要面向:研究生及相关读者。主题:假设我们有两个线性算子T_1,T_2,使得T_2^{-1} - T_1^{-1}是秩1。我们想知道的是如何用T_2^{-1} - T_1^{-1}和(z-T_1)^{-1}表示(z-T_2)^{-1}。关键词:M.G.克莱因公式,有限秩扰动.

英文摘要:

This paper is a didactic comment (a transcription with variations) to the paper of S.R. Foguel {\it Finite Dimensional Perturbations in Banach Spaces}. Addressed, mainly: postgraduates and related readers. Subject: Suppose we have two linear operators, T_1, T_2, so that T_2^{-1} - T_1^{-1} is rank-one. What we want to know is how we can express (z-T_2)^{-1} in terms of T_2^{-1} - T_1^{-1} and (z-T_1)^{-1} . Keywords: M.G.Krein's Formula, Finite Rank Perturbations.
