报告摘要：

The full symmetric Toda system is a straightforward generalisation of the standard open Toda chain. It yields an integrable Hamiltonian system on the space of real symmetric matrices and its generalisations. The properties of this system, its stable points and trajectories, its first integrals and symmetries are closely related to the algebraic and geometric properties of real semisimple Lie groups and their flag spaces. In my talk I will make a survey of these properties and ask few questions. Based on a series of works joint with Yu.Chernyakov, D.Talalaev and A.Sorin
