本文从非紧对称空间上等距作用的观点,猜想了任意李群接纳左不变Ricci孤子的一个障碍。我们还构造了李群的例子,肯定的猜想,在任何尺寸大于2。
In this paper, we conjecture an obstruction for arbitrary Lie groups to admit left-invariant Ricci solitons, from the viewpoint of isometric actions on noncompact symmetric spaces. We also construct examples of Lie groups that affirm the conjecture, in any dimension greater than two.
