Some identities for determinants of structured matrices
Estelle L. Basor, Torsten Ehrhardt
In this paper we establish several relations between the determinants of the following structured matrices: Hankel matrices, symmetric Toeplitz + Hankel matrices and Toeplitz matri…

Invertibility of Toeplitz + Hankel Operators and Singular Integral Operators with Flip - The case of smooth generating functions
Torsten Ehrhardt
It is well known that a Toeplitz operator is invertible if and only if its symbols admits a canonical Wiener-Hopf factorization, where the factors satisfy certain conditions. A sim…
