Dyson's constant in the asymptotics of the Fredholm determinant of the sine kernel

الأصل · EN

We prove that the asymptotics of the Fredholm determinant of I-Kα, where Kα is the integral operator with the sine kernel (x-y)/(x-y)/π on the interval [0,α] is given by a formula which was conjectured by F.J. Dyson. The first and second order asymptotics as well as the higher order asymptotics except for the constant term have already been proved. In this paper we thus determine the constant term.
