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…

A classification of smooth embeddings of 4-manifolds in 7-space, II
Diarmuid Crowley, Arkadiy Skopenkov
Let N be a closed, connected, smooth 4-manifold with H_1(N;Z)=0. Our main result is the following classification of the set E^7(N) of smooth embeddings N->R^7 up to smooth isotopy.…
