Variable-coefficient Toeplitz Matrices with Symbols beyond the Wiener Algebraway from the minimal requirement in the case of constant coefficients. The purpose of this paper is to uncover some phenomena beyond the Wiener condition. We provide counterexamples on the one hand and prove easy-to-check sufficient conditions for boundedness on the other.

A Priori Estimates on the Structured Conditioning of Cauchy and Vandermonde Matrices, we improve known estimates for Vandermonde matrices with generic real nodes; twe consider in detail Vandermonde matrices with nonnegative or symmetric nodes; and we extend the analysis to the class of complex Cauchy-Vandermonde matrices.

QR-factorization of Displacement Structured Matrices Using a Rank Structured Matrix Approachsing scheme for the recursive construction of a diagonal plus semiseparable matrix of semiseparability rank ., where . is equal to the given displacement rank. The complexity is ..n.) operations in the general case, and ..) operations in the Toeplitz- and Hankel-like case, where n denotes the matrix size. Numerical experiments are provided.

Georg Heinig November 24, 1947 - May 10, 2005 A Personal Memoir and Appreciations. As associate editor of the journal Linear Algebra and its Applications since his appointment in 1991 he contributed much to the journal’s success by his valuable and extensive work. In what follows I want to try to capture some aspects of this mathematical life and his personality.
