Autour des résultats d'annulation cohomologique de Scorichenko
Aurélien Djament
The ain of this note is to make available the unpublished proof of Scorichenko of the isomorphism between stable K-theory and functor homology for polynomial coefficients over an a…
On the homology of the space of singular knots
Hossein Abbaspour, David Chataur
In this paper we introduce various associative products on the homology of the space of knots and singular knots in . We prove that these products are related through a desing…
Sur l'homologie des groupes orthogonaux et symplectiques à coefficients tordus
Aurélien Djament, Christine Vespa
We compute the stable homology of orthogonal and symplectic groups over a finite field k with coefficients coming from an usual endofunctor F of k-vector spaces (exterior, symmetri…
Obstruction classes of crossed modules of Lie algebroids and Lie groupoids linked to existence of principal bundles
Camille Laurent-Gengoux, Friedrich Wagemann
Let K be a Lie group and P be a K-principal bundle on a manifold M. Suppose given furthermore a central extension 1\to Z\to \hat{K}\to K\to 1 of K. It is a classical question wheth…
