On the asymptotics of certain Wiener-Hopf-plus-Hankel determinants
Estelle L. Basor, Torsten Ehrhardt
In this paper we determine the asymptotics of the determinants of truncated Wiener-Hopf plus Hankel operators as tends to infinity for symbols $a(x)=(x…
Factorization of a class of Toeplitz + hankel operators and the A_p-condition
Estelle L. Basor, Torsten Ehrhardt
Let be the Toeplitz plus Hankel operator acting on $H^p(\T)$ with generating function $ϕ\in L^\iy(\T)$. In a previous paper we proved that is invertible if…
On the Determinant of a Certain Wiener-Hopf + Hankel Operator
Estelle L. Basor, Torsten Ehrhardt, Harold Widom
We establish an asymptotic formula for determinants of truncated Wiener-Hopf+Hankel operators with symbol equal to the exponential of a constant times the characteristic function o…
Wiener-Hopf determinants with Fisher-Hartwig symbols
Estelle L. Basor, Harold Widom
With localization techniques one can obtain general limit theorems for Toeplitz determinants with Fisher-Hartwig singularities from the asymptotics for any symbol with one singular…
Factorization theory for a class of Toeplitz + Hankel operators
Estelle Basor, Torsten Ehrhardt
In this paper we study operators of the form where and are the Toeplitz and Hankel operators acting on $H^p(\T)$ with generating function $ϕ\in L^\iy…
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…
