结构矩阵的定理与反例
Theorems and counterexamples on structured matrices
摘要：
第1章的主题是GKK $τ$ -矩阵和相关主题。第2章致力于有界可逆矩阵集合，以及算子范数和样条逼近的应用。各种结构矩阵（Toeplitz，Hessenberg，Hankel，Cauchy等）在整个论文中被广泛使用。
英文摘要：
The subject of Chapter 1 is GKK $τ$-matrices and related topics. Chapter 2 is devoted to boundedly invertible collections of matrices, with applications to operator norms and spline approximation. Various structured matrices (Toeplitz, Hessenberg, Hankel, Cauchy, and other) are used extensively throughout the thesis.
