Generalized inversion of Toeplitz-plus-Hankel matrices

A generalized inversion of block T+H matrix is obtained for the first time. In a particular case when T+H matrix is invertible, the method allows to obtain its inverse matrix without an additional condition of invertibility of the corresponding T-H matrix.

Set of Uniform Convergence for the Last Intermediate Row

Let a(z) be a meromorphic function having in the disk |z|<R precisely λpoles. In this work for the (λ-1)th row of the Padé table of a(z) the set of uniform convergence is explicitly obtained. The present note is a supplement to the previous work of the author (J. Approx. Theory, 123(2003), 160-207).
