The stack of formal groups in stable homotopy theory

Zusammenfassung

We construct the algebraic stack of formal groups and use it to provide a new perspective onto a recent result of M. Hovey and N. Strickland on comodule categories for Landweber exact algebras. This leads to a geometric understanding of their results as well as to a generalisation. (c) 2007 Elsevier Inc. All rights reserved.
