Poincare duality and TQFT structures for loop spaces

Aug 31, 2022, 10:10 AM


Kai Cieliebak (Augsburg)


This talk is about ongoing joint work with Nancy Hingston and Alexandru Oancea.
I will explain how various puzzles in string topology get resolved in terms of symplectic geometry: Loop space homology and cohomology are merged into a larger space, Rabinowitz Floer homology, which carries the structure of a graded TQFT and satisfies Poincare duality.
