Subalgebras that cover or avoid chief factors of Lie algebras
arXiv:1311.7270
Abstract
We call a subalgebra of a Lie algebra a -subalgebra of if for any chief factor of , we have or . In this paper we investigate some properties of such subalgebras and obtain some characterizations for a finite-dimensional Lie algebra to be solvable under the assumption that some of its maximal subalgebras or -maximal subalgebras be -subalgebras.
