Abstract
In the paper, Lie algebras having bases of a special form (nice and beautiful bases) are considered. For nice bases, it is proved that, in a chosen nilpotent Lie algebra, their number (up to equivalence) is finite. For some Lie algebras of low dimension, it is shown that, when passing from a complex Lie algebra to its realification, the property to have a beautiful basis is lost.

有限维李代数中的几类基
摘要
在本文中,考虑了具有特殊形式的基(漂亮且美丽的基)的李代数。对于好基,证明了在选定的幂零李代数中,它们的数量(直到等价)是有限的。对于一些低维的李代数,结果表明,当从复杂的李代数过渡到其实现时,拥有美丽基础的性质就消失了。
