The Weyl transform of a compactly supported distribution

Abstract

If $T$ is a compactly supported distribution on $\mathbb{R}^{2n}$, then the Weyl transform of $T$ is $p$-power traceable if and only if the Fourier transform of $T$ is $p$-power integrable, and the Weyl transform of $T$ is a compact operator if and only if the Fourier transform of $T$ vanishes at infinity.
