Non-Abelian Cohomology and Extensions of Lie Algebras
Journal of Lie Theory, Volume 18 (2008) no. 2, pp. 413-432
We introduce the second non-abelian cohomology of Lie algebras with coefficients in crossed modules using the generalised notion of Lie algebra of derivations, and establish a relationship of this cohomology with Lie algebra extensions by crossed modules. We extend the seven-term exact non-abelian cohomology sequence of Guin to a nine-term exact sequence.
