DESCRIPTION:I will state some recent results about homological
stability of diffeomorphism groups of manifolds a
nd 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 essenti
al to the proof. Finally I will sketch the proof o
f the high-connectivity of the splitting complexes
\, which is the most substantial part of the whole
argument.
