高度弯曲的轨道空间
Highly curved orbit spaces
摘要：
已知单位球面上等距作用的轨道空间的截面曲率（在正则部分上）的下确界在上有界$4$ .我们表明，下确界是$1$的“大多数”行动，并确定的情况下，它是大于$1$。
英文摘要：
It is known that the infimum of the sectional curvatures (on the regular part) of orbit spaces of isometric actions on unit spheres in bounded above by $4$. We show that the infimum is $1$ for "most" actions, and determine the cases in which it is bigger than $1$.
