String topology of finite groups of Lie type
Jesper Grodal, Anssi Lahtinen
We show that the mod cohomology of any finite group of Lie type in characteristic different from admits the structure of a module over the mod cohomology o…
Group cohomology and control of p-fusion
David Benson, Jesper Grodal, Ellen Henke
We show that if an inclusion of finite groups H < G of index prime to p induces a homeomorphism of mod p cohomology varieties, or equivalently an F-isomorphism in mod p cohomology,…
The classification of p-compact groups and homotopical group theory
Jesper Grodal
We survey some recent advances in the homotopy theory of classifying spaces, and homotopical group theory. We focus on the classification of p-compact groups in terms of root data…
The Steenrod problem of realizing polynomial cohomology rings
Kasper K. S. Andersen, Jesper Grodal
In this paper we completely classify which graded polynomial R-algebras in finitely many even degree variables can occur as the singular cohomology of a space with coefficients in…
The classification of 2-compact groups
Kasper K. S. Andersen, Jesper Grodal
We prove that any connected 2-compact group is classified by its 2-adic root datum, and in particular the exotic 2-compact group DI(4), constructed by Dwyer-Wilkerson, is the only…
The classification of 2-compact groups (talk summary)
Kasper K. S. Andersen, Jesper Grodal
This is a summary of a talk given at the "Conference on Pure and Applied Topology", Isle of Skye, June 24, 2005. It contains an announcement and sketch of proof of the classificati…
