Reduced fusion systems over 2-groups of small order
Kasper K. S. Andersen, Bob Oliver, Joana Ventura
We prove, when is a -group of order at most , that each reduced fusion system over is the fusion system of a finite simple group and is tame. It then follows that e…
The C*-algebra of an affine map on the 3-torus
Kasper K. S. Andersen, Klaus Thomsen
We study the C*-algebra of an affine map on a compact abelian group and give necessary and sufficient conditions for strong transitivity when the group is a torus. The structure of…
Spaces with Noetherian cohomology
Kasper K. S. Andersen, Natalia Castellana, Vincent Franjou +2
Is the cohomology of the classifying space of a p-compact group, with Noetherian twisted coefficients, a Noetherian module? This note provides, over the ring of p-adic integers, su…
Reduced, tame and exotic fusion systems
Kasper K. S. Andersen, Bob Oliver, Joana Ventura
We define here two new classes of saturated fusion systems, reduced fusion systems and tame fusion systems. These are motivated by our attempts to better understand and search for…
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…
