Reading seminar on the Hopf conjecture W39

This reading seminar concerns all good things surrounding the Hopf
conjecture (Betti numbers of apherical manifolds), starting with a paper
of Leung and Reiner that connects it to the signature of the
Hodge-Riemann form of a toric variety.
Group members are expected to be more than just interested. We
touch on algebraic geometry and geometric group theory and topology
too. Please contact Karim Alexander Adiprasito: If wish to participate.
