Lennart Meier (VIRGINIA): Homotopy Fixed Points of Landweber Exact Spectra (17/06/2014)

Abstract

Rognes introduced the notion of a Galois extension of ring spectra about 10 years ago. He observed that the map from real to complex K-theory is an example of a Galois extension. I will present a more general theorem on group actions on Landweber exact spectra, producing new Galois extensions. Examples involving topological modular forms will be given. If time permits, possible applications to Anderson duality will be discussed.
