Factorization of a class of Toeplitz + hankel operators and the A_p-condition

Estelle L. Basor, Torsten Ehrhardt

Let $M (ϕ) = T (ϕ) + H (ϕ)$ 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 $M (ϕ)$ 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 $I - K_{α}$ , where $K_{α}$ is the integral operator with the sine kernel $sin (x - y) / (x - y) / π$ on the interval $[0, α]$ is given…
