Riemann’s moduli space M_g classifies families of genus g Riemann surfaces, and is also a model for the classifying space of the group of diffeomorphisms of a genus g surface. In 1985 Harer proved his celebrated stability theorem, which states that the i-th cohomology of M_g is independent of g, as long as g is large compared with i. More recently, Madsen and Weiss computed the cohomology of M_g in this large genus regime, confirming a conjecture of Mumford.
I will discuss recent joint work with S. Galatius, where we establish an analogous pair of results for manifolds of higher even dimension.
