与根系有关的某些动力系统的小振荡频率
On frequencies of small oscillations of some dynamical systems associated with root systems
摘要：
在F. Calogero和作者[Commun. Math.Phys.59（1978）109-116]中，我们找到了Sutherland系统（$A_l$情况）的小振荡频率公式，本文给出了这个公式在任意根系情况下的推广。
英文摘要：
In the paper by F. Calogero and author [Commun. Math. Phys. 59 (1978) 109-116] the formula for frequencies of small oscillations of the Sutherland system ($A_l$ case) was found. In present note the generalization of this formula for the case of arbitrary root system is given.
