Endpoint Schatten class properties of commutators

Rupert L. Frank, Fedor Sukochev, Dmitriy Zanin

We study trace ideal properties of the commutators $[(-\Delta {)}^{\frac{\epsilon }{2}},M_f]$ of a power of the Laplacian with the multiplication operator by a function $f$ on ${\mathbb{R}}^d$. For a c…
