查询词典 singular chain complex

This chapter clarifies the nested relationship between the matrix family of unitary, orthogonal, Givens, Householder, permutation, and row or column symmetric matrices. A precise correspondence of the singular values and singular vectors between the unitary-symmetric matrix and its mother matrix is derived and proved (hence a fast algorithm of singular value decomposition for unitary-symmetric matrix is straightforwardly obtained), and the corresponding perturbation bound is provided.

This paper doesn't research on the general theory and method for valuation, while I try to find a unique way to improve and apply the traditional valuation theory and method in order to meet the need of the new background and new environment. Putting valuation into the value chain background, research on corporate valuation of node corporations of value chain and the value distribution in a value chain, through which the valuation result will reflect the value aim of those companies in value chain and establish a basis for companies to make sure their strategic positions in value chain and to plan their strategy are the main creations of this paper.
