Andreas Stavrou (University of Chicago) — Configuration spaces of surfaces and the Johnson filtration

The mapping class group of a surface acts naturally on the homology of the configuration spaces of the surface. The representations that arise vary in complexity with the number of configuration points and with the flavour of the configuration spaces. In this talk, I will relate this complexity with the Johnson filtration of the mapping class group.
