Classifying spaces of infinity-sheaves on manifolds
I will describe how one can associate a “classifying space” to an infinity (alias homotopy) sheaf on the category of manifolds. This is based on joint work with D. Berwick-Evans and D. Pavlov (arXiv:1912.10544.), and is a homotopical strenghtening of a theorem of Madsen and Weiss. Examples abound.
