"A Solvable Hamiltonian System" Integrability and Action-Angle Variables
V. Karimipour
Abstract
We prove that the dynamical system charaterized by the Hamiltonian H = λN ΣjN pj + μΣj,kN (pj pk)1 2 \ cos [ ν( qj - qk)] \ proposed and studied by Calogero [1,2] is equivalent to a system of non-interacting harmonic oscillators. We find the explicit form of the conserved currents which are in involution. We also find the action-angle variables and solve the initial value problem in simple form.
