The Non-Abelian Tensor and Exterior Products of Crossed Modules of Lie Algebras
Journal of Lie Theory, Volume 28 (2018) no. 1, pp. 169-185
The notions of non-abelian tensor and exterior products of two ideal crossed submodules of a given crossed module of Lie algebras are introduced and some of their fundamental properties are established. Using the obtained results, we also give a new description of the second homology of Lie algebra crossed modules.
