一类复单李代数的保根正交变换群
A Class of Complex Simple Lie Algebra Remain the Same Root Orthogonal Transformation Groups
摘要
Abstract
The group G which keep the same root and the Weyl group W are closely associates in the simple lie algebra. On the one hand,we have that W is the maximal normal sub-group of G, as well we get the quotient group. On the other hand, we structure maximal normal subgroup. That shows that W is not the only maximal subgroup of G.关键词
