On frequencies of small oscillations of some dynamical systems associated with root systems
A. M. Perelomov
Abstract
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 (Al case) was found. In present note the generalization of this formula for the case of arbitrary root system is given.
