One hundred years after its birth, quantum mechanics remains one of the most powerful and successful theories in all of ...

Commutators and Compactness in Schrödinger Operators Publication Trend The graph below shows the total number of publications each year in Commutators and Compactness in Schrödinger Operators.

In this paper we characterize when the semi-commutator TfTg — Tfg of two Toeplitz operators Tf and Tg on the Hardy space of the bidisc is zero. We also show that there is no finite rank ...

We prove that the operator norm on weighted Lebesgue space L2(w) of the commutators of the Hilbert, Riesz and Beurling transforms with a BMO function b depends quadratically on the A2-characteristic ...
