With the motivation of the undirected graph and bipartite partition, some new estimations for singular values of a matrix were presented. 摘要利用矩阵的无向图及二部分划,给出了新的复合型矩阵奇异值估计式,改进了已有的相应结果。
The problem of singular values of matrices is considered and some extremum properties of singular values are investigated. 摘要考虑了矩阵奇异值的相关问题,研究了其极值性质,并得出了一些特殊情形下的结果。
