MPIM Topology Seminar The method of "configuration space integrals" gives invariants of certain smooth fiber bundles. It was shown by Watanabe (2018) that these invariants can detect exotic fiber bundles. I will discuss the relationship between this and the philosophy "a diffeomorphism lifts to maps between (compactified) configuration spaces, but a homeomorphism does not".
