| Résume | In this talk I will present some recent developments building on the topic of the paper https://arxiv.org/abs/1605.02721. I will introduce the concept of absolute and relative Calabi-Yau structures on dg categories/algebras defined by Brav and Dyckerhoff, and then show how these structures come from a more general definition of an orientation on a (co)sheaf of categories. This will be a noncommutative version of the usual notion of an orientation on a manifold, and gives the desired Calabi-Yau structures upon integration. |
