关于Eisenbud和Wigner的R-矩阵的一般方法

On Eisenbud's and Wigner's R-matrix: A general approach

J. Behrndt, H. Neidhardt, E. R. Racec, P. N. Racec, U. Wulf

摘要:

本文的主要目的是严格地处理Wigner和Eisenbud的$R$ -矩阵方法,该方法适用于由两个具有有限亏指数的对称算子的自伴扩张构成的散射系统的散射矩阵.在边界三元组和相关的Weyl函数的框架下,$R$ -矩阵方法的抽象推广的发展和结果被应用到薛定谔算子的实轴上。

英文摘要:

The main objective of this paper is to give a rigorous treatment of Wigner's and Eisenbud's $R$-matrix method for scattering matrices of scattering systems consisting of two selfadjoint extensions of the same symmetric operator with finite deficiency indices. In the framework of boundary triplets and associated Weyl functions an abstract generalization of the $R$-matrix method is developed and the results are applied to Schrödinger operators on the real axis.
