Explore the intriguing world of coproduct structures in Floer theory and string topology through this 52-minute conference talk by Lea Kenigsberg from Columbia University. Delve into the significance of these structures and discover a newly defined coproduct structure on the symplectic cohomology of Liouville manifolds. Learn about Kenigsberg's thesis work in progress as she computes an example to demonstrate the non-triviality of this structure. Gain insights into this elusive topic and its importance in the field of symplectic geometry during this Western Hemisphere Virtual Symplectic Seminar presentation.
