Description
I will explain joint work with Oscar Randal-Williams, in which we study Torelli groups of the higher-dimensional analogues of surfaces. This is done by combining the work of Galatius--Randal-Williams on stable moduli spaces of manifolds with Goodwillie--Klein--Weiss embedding calculus. Particular attention will be given to the relationship between our results and graph complexes.
