Algebraic geometry of the sphere at infinity, polyhedral de Rham theory and l^2 vanishing conjectures (Karim Adiprasito, Copenhagen)

I will discuss a conjecture of Singer concerning the vanishing of L^2 cohomology on non-positively curved manifolds, and relate it to Hodge theory on a Hilbert space that arises as the limit of Chow rings of certain complex varieties.
