If you have a question about this talk, please contact Oscar Randal-Williams.

I will state some recent results about homological stability of diffeomorphism groups of manifolds and give an outline of their proof. In particular, I will talk about the connection to E_k-algebras, and about certain complexes, called “splitting complexes”, whose high-connectivities are essential to the proof. Finally I will sketch the proof of the high-connectivity of the splitting complexes, which is the most substantial part of the whole argument.
