论文摘要
关于卷积操作员以及$ 1 $ -D(一维)情况的Toeplitz(和Block Toeplitz)矩阵的反转结果是经典的,并且有许多应用程序。去年,我们考虑了$ 2 $ -D的toeplitz-block toeplitz(TBT)矩阵的情况,描述了一个最小信息,这是恢复反矩阵的必要信息,并给出了反矩阵的完整表征。现在,我们开发了更复杂的块TBT矩阵和$ 3 $ -D toeplitz矩阵的方法。
The results on the inversion of convolution operators as well as Toeplitz (and block Toeplitz) matrices in the $1$-D (one-dimensional) case are classical and have numerous applications. Last year, we considered the $2$-D case of Toeplitz-block Toeplitz (TBT) matrices, described a minimal information, which is necessary to recover the inverse matrices, and gave a complete characterisation of the inverse matrices. Now, we develop our approach for the more complicated cases of block TBT-matrices and $3$-D Toeplitz matrices.
