In this paper, a study is made on two well-known operator matrices; the Rhaly operator Rₐ and the generalized difference operator Δab. Firstly, some compactness results for the operators Rₐ and Δab, ...
An algorithm for determining the triangular decomposition H = R * DR of a Hankel matrix H using O(n 2) operations is derived. The derivation is based on the Lanczos algorithm and the relation between ...
