The e-invariant and the spectrum of the Lapacian for compact nilmanifolds covered by Heisenberg groups.
Topological charges and high dimensional instantons
Vector fields on the Sato Grassmannian.
An explicit basis of the space of global vector fields on the Sato Grassmannian is computed and the vanishing of the first cohomology group of the sheaf of derivations is shown.
-periodic homotopy groups of the Dwyer-Wilkerson space.
