[Petr Somberg]

 This is just the gentle remainder of our seminar starting soon!

> Cohomology in algebra, geometry, physics and statistics
> Wednesday, 7 May 2025 - 13:30 to 14:30
> Place: Institute of Mathematics of ASCR, Žitná 25, Praha 1, the  blue
> lecture  room + ZOOM meeting
>
> Speaker: Leonid Ryvkin, Université Claude Bernard Lyon 1
> Title: Vector bundles over unordered configuration spaces
> Abstract
>
>
> I will describe a recent construction of a symmetrized external tensor
> product of vector bundles of unordered configuration spaces (over some
> fixed manifold M). Together with the usual tensor product this
> construction induces a 2-monoidal structure on these vector bundles and
> naturally appears when 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-compact, even when the initial manifold M is.
>
> based on joint work with Alessandra Frabetti and Olga Kravchenko.
