Structure and Homotopy of Configuration Spaces (SHoCoS)

December 1st, 2022 – November 30th, 2027


This is a project of fundamental research in mathematics, specifically, algebraic topology, homotopical algebra, and quantum algebra. It is concerned with configuration spaces, which consist in finite sequences of pairwise distinct points in a manifold. Over the past couple of decades, strides have been made in the study and computation of the homotopy types of configuration spaces, i.e., their shape up to continuous deformation. These advances were possible thanks to the rich structure of configuration spaces, which comes from the theory of operads. Moreover, a new theory, factorization homology, allowed the use of configuration spaces to compute topological field theories, topological invariants of manifolds inspired by physics. Our purpose is to exploit the full operadic structure of configuration spaces to obtain new kinds of stabilizations in the homotopy types of configuration spaces, and to use this stability to effectively compute topological field theories from deformation quantization.

This project funded by the Agence Nationale de la Recherche (ANR) under the identifier ANR-22-CE40-0008. It is hosted at Université Paris Cité and it is managed by the CNRS. The overall budget of the project is 214 k€.
