A stable splitting for spaces of commuting elements in unitary groups

Alejandro Adem, José Manuel Gómez, Simon Gritschacher

We prove an analogue of Miller's stable splitting of the unitary group for spaces of commuting elements in . After inverting , the space $\text{Hom}(\mathbb{Z}^n,U…

Twisted equivariant K-theory of compact Lie group actions with maximal rank isotropy

Alejandro Adem, José Cantarero, José Manuel Gómez

We consider twisted equivariant K--theory for actions of a compact Lie group on a space where all the isotropy subgroups are connected and of maximal rank. We show that the…

Free Finite Group Actions on Rational Homology 3--Spheres

Alejandro Adem, Ian Hambleton

We use methods from the cohomology of groups to describe the finite groups which can act freely and homologically trivially on closed 3-manifolds which are rational homology sphere…
