in IM back building, ground floor, blue lecture room + ZOOM meeting
Wednesday, 16. December 2020 - 11:30 to 12:30
I will recall loop spaces, natural structures on their
homology and the relation to symplectic geometry of the cotangent bundle
(specifically to chain level structures defined by counting holomorphic
curves). I will then zoom in on the equivariant case and a chain model
based on de Rham forms and Chern-Simons theory. I will show some
computations and explain how this structure appears in various contexts.


We shall  meet   in  the  blue lecture room   in Zitna 25  and   at ZOOM at the same  time.
The lecture   room and ZOOM shall be opened  at 11.15  and closed  at   13.00.
