论文摘要
我们在矩阵上提供足够的条件，以确保该矩阵的分区存在为两个矢量图像规范的两个子膜片。在矩阵A上的某些弱条件下，我们获得了A分区，并具有极小的$（1，Q）$ - 一量的标准。
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.
