My last trip before the Corona lock down took me to Vienna. I finally had the chance to take David Fajman up on an invitation, which was extended quite a while back (being back in Europe makes these sort of visits so much easier), to give a talk in the Seminar of the Gravitation group of the University of Vienna.
I also took the chance to pop over to the Math department for a quick chat with Roland Donninger about Strichartz estimates and results in my upcoming paper with Felix.
As you can see, for once, I forgot to bring my beloved proton and hence it is missing from my pictures :).
Welcome to my intellectual Universe
