    Stratification and duality for homotopical groups

    We generalize Quillen's FF-isomorphism theorem, Quillen's stratification theorem, the stable transfer, and the finite generation of cohomology rings from finite groups to homotopical groups. As a consequence, we show that the category of module spectra over C∗(BG,Fp)C^*(B\mathcal{G},\mathbb{F}_p) is stratified and costratified for a large class of pp-local compact groups G\mathcal{G} including compact Lie groups, connected pp-compact groups, and pp-local finite groups, thereby giving a support-theoretic classification of all localizing and colocalizing subcategories of this category. Moreover, we prove that pp-compact groups admit a homotopical form of Gorenstein duality.Comment: Corrected discussion of Chouinard's theorem for homotopical groups; accepted for publication in Advances in Mathematic
