Moduli space of metrics of nonnegative sectional/positive Ricci curvature on homotopy real projective spaces

We show that the moduli space of metrics of nonnegative sectional curvature on a smooth closed manifold homotopy equivalent to RP5 has infinitely many connected components. We also discuss corresponding results in higher dimensions for the moduli space of metrics of positive Ricci curvature. The proof uses eta invariants.

Nilpotent structures and collapsing Ricci-flat metrics on K3 surfaces

We exhibit sequences of Ricci-flat K ähler metrics on K3 surfaces which collapse to an interval. There is a corresponding singular fibration from the K3 surface to the interval, with regular fibers diffeomorphic to either
3-tori or Heisenberg nilmanifolds, while each singular fiber is a singular circle bundle over a torus.
