DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PHK-cohomolo
 gy-seminar/132/">Vector bundles over unordered configuration spaces</a>\nb
 y Leonid Ryvkin (Université Claude Bernard Lyon 1) as part of Prague-Hrad
 ec Kralove seminar Cohomology in algebra\, geometry\, physics and statisti
 cs\n\nLecture held in the blue lecture room + ZOOM meeting.\n\nAbstract\nI
  will describe a recent construction of a symmetrized external tensor prod
 uct of vector bundles of unordered configuration spaces (over some fixed m
 anifold M). Together with the usual tensor product this construction induc
 es a 2-monoidal structure on these vector bundles and naturally appears wh
 en trying to construct a geometric model for the multilocal observables in
  field theory. I will also discuss how equipping the configuration with a 
 certain natural bornology can compensate the fact that they are non-compac
 t\, even when the initial manifold M is.\n\nbased on joint work with Aless
 andra Frabetti and Olga Kravchenko.\n
