Compactness of Fourier concentration operators

Helge Jørgen Samuelsen

We present a sufficient condition on sets $E$ and $F$ in $R^{d}$ to ensure compactness of Fourier concentration operators by introducing the notion of sets which are very th…

Fourier-Wigner multipliers and the Bochner-Riesz conjecture for Schatten class operators

Helge Jørgen Samuelsen

In this paper we introduce the notion of Fourier-Wigner multipliers for the Schatten class operators $S^{p}$ , which acts as an extension of classical localisation operators…

A remark on the Weyl quantisation of Paley-Wiener functions

Helge J. Samuelsen

We present a short proof of the fact that the Weyl quantisation of a tempered distribution with compactly supported Fourier transform is in the Schatten $p$ -class if and only if th…
