Nekrasov矩阵的推广
Extention of Nekrasov matrix
摘要
Abstract
The definition of Nekrasov matrix is extended by giving some kinds of new matrix, which are it-layer Nekrasov matrix, generalized κ-layer Nekrasov matrix and κ-layer weak Nekrasov matrix. Futher, by using the properties of matrix and some inequalities techniques, the relationship between these kinds of new matrix and the generalized strictly diagonally dominant matrix is obtained.关键词
