Poincar\'e/Koszul duality
Abstract
We prove a duality for factorization homology which generalizes both usual Poincar\'e duality for manifolds and Koszul duality for En-algebras. The duality has application to the Hochschild homology of associative algebras and enveloping algebras of Lie algebras. We interpret our result at the level of topological quantum field theory.
