At the moment there are many online activities going on …. and here is another one: the Wales Mathematical Physics Zoom Seminar, organized by Edwin Beggs, David Evans, Gwion Evans,Rolf Gohm, Tim Porter.
Why do I mention in particular this one; there are at least two reasons. Today there is a talk by Mikael Rordam around the Connes embedding problem, and next week I will give a talk, on my joint work with Tobias Mai and Sheng Yin of the last years around rational functions of random matrices and operators.
If you are interested in any of this, here is the website of the seminar, where you can find more information.
