Quasi-cyclic displacement and inversion decomposition of a quasi-Toeplitz matrix

We study a class of column upper-minus-lower (CUML) Toeplitz matrices, which are "close" to the Toeplitz matrices in the sense that their (1,−1)-cyclic displacements coincide with φ-cyclic displacement of some Toeplitz matrices. Among others, we derive the inverse formula for CUML Toeplitz...
