abstract:

We conceive higher bundles with connections entirely Lie algebraically by, essentially, extending the Cartan-Ehresmann definition of a connection from Lie algebras to L-infinity algebras. Using this machinery, we study Chern-Simons n-bundles as obstructions to lifts through String-like extensions of L-infinity algebras.
