Characteristics for $E_\infty$ ring spectra

Algebraic Topology 2017-06-02 v5

Abstract

We introduce a notion of characteristic for connective pp-local EE_\infty ring spectra and study some basic properties. Apart from examples already pointed out by Markus Szymik, we investigate some examples built from Hopf invariant 11 elements in the stable homotopy groups of spheres and make some conjectures about spectra for which they may be characteristics; these appear to involve hard questions in stable homotopy theory.
