S-expansions of three-dimensional Lie algebras [PDF]
Maryna NesterenkoS-expansions of three-dimensional real Lie algebras are considered. It is shown that the expansion operation allows one to obtain a non-unimodular Lie algebra from a unimodular one. Nevertheless S-expansions define no ordering on the variety of Lie algebras of a fixed dimension.View original: http://arxiv.org/abs/1212.1820
