李代数的C-理想

C-Ideals of Lie Algebras

David A. Towers

摘要:

李代数L的子代数B称为L的c-理想,如果存在L的理想C使得L = B + C且B \cap C \leq B_L,其中B_L是B中包含的$L$的最大理想.这类似于c-正规子群的概念,它已经被许多作者研究过了。我们得到了c-理想的一些性质,并利用它们给出了可解和超可解李代数的一些特征。我们还对每个一维子代数都是c-理想的李代数进行了分类。

英文摘要:

A subalgebra B of a Lie algebra L is called a c-ideal of L if there is an ideal C of L such that L = B + C and B \cap C \leq B_L, where B_L is the largest ideal of $L$ contained in B. This is analogous to the concept of c-normal subgroup, which has been studied by a number of authors. We obtain some properties of c-ideals and use them to give some characterisations of solvable and supersolvable Lie algebras. We also classify those Lie algebras in which every one-dimensional subalgebra is a c-ideal.
