Lie rackoids integrating Courant algebroids
Camille Laurent-Gengoux, Friedrich Wagemann
We construct an infinite dimensional Lie rackoid Y which hosts an integration of the standard Courant algebroid. As a set, Y = C ([0, 1], T * M) for a compact manifold M.…

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…
