Finite group actions on Kervaire manifolds
Diarmuid Crowley, Ian Hambleton
The (4k+2)-dimensional Kervaire manifold is a closed, piecewise linear (PL) manifold with Kervaire invariant 1 and the same homology as the product of two (2k+1)-dimensional sphere…
Recognizing products of surfaces and simply connected 4-manifolds
Ian Hambleton, Matthias Kreck
We give necessary and sufficient conditions for a closed smooth 6-manifold N to be diffeomorphic to a product of a surface F and a simply connected 4-manifold M in terms of basic i…
Group actions on spheres with rank one isotropy
Ian Hambleton, Ergun Yalcin
Let G be a rank two finite group, and let $\cH$ denote the family of rank one p-subgroups of G, at all primes where G has p-rank two. We show that a rank two finite group G which s…
More examples of discrete co-compact group actions
Ian Hambleton, Erik K. Pedersen
We survey some results and questions about free actions of infinite groups on products of spheres and euclidean spaces, and give some new co-compact examples.
