Decomposition of the Nonabelian Tensor Product of Lie Algebras via the Diagonal Ideal

Decomposition of the Nonabelian Tensor Product of Lie Algebras via the Diagonal Ideal We prove a theorem of splitting for the nonabelian tensor product $$L \otimes N$$ L ⊗ N of a pair (L, N) of Lie algebras L and N in terms of its diagonal ideal $$L \square N$$ L □ N and of the nonabelian exterior product $$L \wedge N$$ L ∧ N . A similar circumstance was described few years ago in the special case $$N=L$$ N = L . The interest is due to the fact that the size of $$L \square N$$ L □ N influences strongly the structure of $$L \otimes N$$ L ⊗ N . http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Bulletin of the Malaysian Mathematical Sciences Society Springer Journals

Abstract

We prove a theorem of splitting for the nonabelian tensor product $$L \otimes N$$ L ⊗ N of a pair (L, N) of Lie algebras L and N in terms of its diagonal ideal $$L \square N$$ L □ N and of the nonabelian exterior product $$L \wedge N$$ L ∧ N . A similar circumstance was described few years ago in the special case $$N=L$$ N = L . The interest is due to the fact that the size of $$L \square N$$ L □ N influences strongly the structure of $$L \otimes N$$ L ⊗ N .
