The ghost and weak dimensions of rings and ring spectra

Algebraic Topology 2009-04-13 v2 Rings and Algebras

Abstract

The primary object of this paper is to prove the conjecture of the authors from a previous paper, explaining how to recover the weak dimension of a ring from its derived category. In the process, we develop a theory of weak dimension, which we call ghost dimension, for the generalized rings, known as ring spectra, that arise in algebraic topology.
