The spectral density of Hankel operators with piecewise continuous symbols

Emilio Fedele

In 1966, H. Widom proved an asymptotic formula for the distribution of eigenvalues of the $N \times N$ truncated Hilbert matrix for large values of $N$ . In this paper, we extend thi…

On determinants identity minus Hankel matrix

Emilio Fedele, Martin Gebert

In this note, we study the asymptotics of the determinant $det (I_{N} - β H_{N})$ for $N$ large, where $H_{N}$ is the $N \times N$ restriction of a Hankel matrix $H$ with finitely many jum…

Weighted integral Hankel operators with continuous spectrum

Emilio Fedele, Alexander Pushnitski

Using the Kato-Rosenblum theorem, we describe the absolutely continuous spectrum of a class of weighted integral Hankel operators in $L^{2} (R_{+})$ . These self-adjoint operator…
