Stably diffeomorphic manifolds and l_{2q+1}(Z[π])
Diarmuid Crowley, Jörg Sixt
The monoids l_{2q+1}(Z[π]) detect s-cobordisms amongst certain bordisms between stably diffeomorphic 2q-dimensional manifolds and generalise the Wall simple surgery obstruction gro…

The classification of highly connected manifolds in dimensions 7 and 15
Diarmuid J. Crowley
Let P be a closed smooth (4j-2)-connected 8j-manifold. We complete Wilkens' classification of the manifolds P for j = 1,2 and give an alternative proof to Wall's classification of…

A classification of -bundles over
Diarmuid Crowley, Christine M. Escher
We classify the total spaces of bundles over the four sphere with fiber a three sphere up to orientation preserving and reversing homotopy equivalence, homeomorphism and diffeomorp…
