Abstract

Let AA be an E\mathbf{E}_{\infty}-ring spectrum over the rational numbers. If AA satisfies a noetherian condition on its homotopy groups π(A)\pi_*(A), we construct a collection of E\mathbf{E}_{\infty}-AA-algebras that realize on homotopy the residue fields of π(A)\pi_*(A). We prove an analog of the nilpotence theorem for these residue fields. As a result, we are able to give a complete algebraic description of the Galois theory of AA and of the thick subcategories of perfect AA-modules. We also obtain partial information on the Picard group of AA.
