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…
Dyson's constant in the asymptotics of the Fredholm determinant of the sine kernel
Torsten Ehrhardt
We prove that the asymptotics of the Fredholm determinant of , where is the integral operator with the sine kernel on the interval is given…
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…
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…
