Tigran Hakobyan, David Karakhanyan, Olaf Lechtenfeld

摘要:

本文利用SL(2,R)代数及其表示,研究了一般共形力学系统在有和无约束调和势时的运动积分,以及相关的角度子系统的运动积分.特别是,通过张量积的两个表示,我们构造新的运动积分从旧的。此外,时间周期观测量(包括积分)的角度子系统显式相关的限制谐波势的整个系统。的技术说明了合理的Calogero模型和它们的角度子系统,在那里他们概括了已知的方法获得保守的费用超出刘维的。

英文摘要:

We investigate the integrals of motion of general conformal mechanical systems with and without confining harmonic potential as well as of the related angular subsystems, by employing the SL(2,R) algebra and its representations. In particular, via the tensor product of two representations we construct new integrals of motion from old ones. Furthermore, the temporally periodic observables (including the integrals) of the angular subsystem are explicitly related to those of the full system in a confining harmonic potential. The techniques are illustrated for the rational Calogero models and their angular subsystems, where they generalize known methods for obtaining conserved charges beyond the Liouville ones.
