Research at the Institute of Quantum Optics focuses on highly controlled interaction of light and matter. Typical topics are the physics of ultracold quantum gases, quantum logic spectroscopy based on cooling and trapping of ions dealing with fundamental principles of physics, the physics of ultrashort laser pulses and the control of plasmas in the sub-femto region and applications of nonlinear optics in medical therapy and diagnostics. The institute also provides central parts of the education within the Bachelor and Master courses in physics and related topics.

Online talk, 03:00 p.m. Prof. Dr. Brett Wick Washington University St. Louis Commutators and Bounded Mean Oscillation

Commutators and Bounded Mean Oscillation

 

We will discuss some recent results about commutators of certain Calderon-Zygmund operators and BMO spaces and how these generate bounded operators on Lebesgue spaces. Results on the Heisenberg group, pseudoconvex domains with $C^2$ boundary, and other examples will be explained. This talk is based on joint collaborative work
