The semisimplicity of pointed YD Lie algebras was characterized by means of Killing forms.
利用Killing型来判断点YD-李代数的半单性,得出了如下结论:如果有限维点YD-李代数L的Killing型是非退化的,那么L是半单的,并且L是它本身的所有极小YD-理想的直和;这些极小YD-理想所对应的Killing型两两正交。
By describing general superfluous convex l-subgroups in this paper, we prove the following results: If G is a normal-valued l-group, then (1)T= {x∈G|x<<u, u is a strong unit of G} ; (2) T = 0 iff G is l- isomorphic to a subdirect product of simple l-groups with semisimplicity.
证明了如下结果:如 果G是正规值l-群,则(1)T={x∈G|x<
