摘要: 无限次微扰理论是求解无序体系格林函数的理论方法。此方法是吴式玉教授及其合作者们用“图式法”获得的。本文采用把矩阵分块,求解子矩阵方程的方法,推导了这一理论的结果,从而给出了这一理论的矩阵代数证明。

Abstract: Recently, Wu and his coworkers formulated an infinite order perturbation theory for solving the Green's function of a disordered system, using a diagrammatic technique. In this paper, the method of matrix partition is used to obtain the same series of recursion relations, thus providing an algebraic proof for the theory.
