Cohomology in algebra, geometry, physicsand statistics
Chain models of string topology coming from symplectic geometry

Place:
in IM back building, ground floor, blue lecture room + ZOOM meeting
Date:
Wednesday, 16. December 2020 - 11:30 to 12:30
Abstract:
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.
