On Matrices that are not Similar to a Toeplitz Matrix and a Family of Polynomials Tewodros AmdeberhaA conjecture from the second author’s paper concerning a family of polynomials is proved and strengthened. A consequence of this is that for any . ≥ 4 there is an . matrix that is not similar to a Toeplitz matrix, which was proved before for odd . and . = 6, 8, 10.

On Extremal Problems of Interpolation Theory with Unique SolutionThe main goal of this paper is to investigate the matrix extremal interpolation problem formulated in Chapter 7 of the monograph . We give natural conditions under which the problem has one and only one solution. The basic idea of the proof is to use the matrix Riccati equation deduced in .

A Traub-like Algorithm for Hessenbergquasiseparable- Vandermonde Matrices of Arbitrary Order.) Traub-like algorithm to invert the associated (.)-...The class of . is garnering a lot of attention recently; it has been found to be useful in designing a number fo fast algorithms. The derivation of our new Traub-like algorithm is also based on exploiting quasiseparable structure of the corresp
