Invariant prime ideals in equivariant Lazard rings
Markus Hausmann, Lennart Meier
Let be an abelian compact Lie group. In this paper we compute the spectrum of invariant prime ideals of the -equivariant Lazard ring, or equivalently the spectrum of points…

Representation-graded Bredon homology of elementary abelian 2-groups
Markus Hausmann, Stefan Schwede
We calculate the representation-graded Bredon homology rings of all elementary abelian 2-groups with coefficients in the constant mod-2 Mackey functor. We exhibit minimal presentat…

The universal property of bordism of commuting involutions
Markus Hausmann, Stefan Schwede
We propose a formalism to capture the structure of the equivariant bordism rings of smooth manifolds with commuting involutions. We introduce the concept of an oriented el…
