摘 要:
在块对角占优矩阵和广义块对角占优矩阵的概念的基础上,引入了块局部双对角占优矩阵的概念,应用矩阵分块方法,给出了判定分块矩阵为块广义对角占优矩阵的充分条件。[著者文摘]

Abstract:
Based on the concept of block diagonally dominant and block generalized diagonally dominant, we give the definition of block locally double-diagonaUy dominant matrix, and by using the method of block matrices,some sufficient conditions for block generalized diagonally dominant matrix are given.[著者文摘]
Key words:
Generalized block diagonally dominant matrix; Block locally double-diagonally dominant matrix;Block eigenvalue
