Derived induction and restriction theory
Let be a finite group. To any family of subgroups of , we associate a thick –ideal of the category of –spectra with the property that every –spectrum in (which we call –nilpotent) can be reconstructed from its underlying –spectra as varies over . A similar result holds for calculating –equivariant homotopy classes of maps into such spectra via an appropriate homotopy limit spectral sequence. In general, the condition implies strong collapse results for this spectral sequence as well as its dual homotopy colimit spectral sequence. As applications, we obtain Artin- and Brauer-type induction theorems for –equivariant –homology and cohomology, and generalizations of Quillen’s –isomorphism theorem when is a homotopy commutative –ring spectrum.
We show that the subcategory contains many –spectra of interest for relatively small families . These include –equivariant real and complex –theory as well as the Borel-equivariant cohomology theories associated to complex-oriented ring spectra, the –local sphere, the classical bordism theories, connective real –theory and any of the standard variants of topological modular forms. In each of these cases we identify the minimal family for which these results hold.
