We give sufficient conditions on a matrix A ensuring the existence of a partition of this matrix into two submatrices with extremely small norm of the image of any vector. Under some weak conditions on a matrix A we obtain a partition of A with the extremely small $(1,q)$-norm of submatrices.

用极小的算子范数将矩阵分解为两个子矩阵

我们在矩阵 A 上给出了充分条件,确保该矩阵存在一个分割为两个子矩阵,其中任何向量的图像范数都非常小。在矩阵 A 上的一些弱条件下,我们获得了 A 的分区,其中子矩阵的 $(1,q)$-范数非常小。
