Birkhoff normal form for the periodic Toda lattice
with potential V (x) = γe + V1x + V2 and γ, δ, V1, V2 ∈ R constants. The Toda lattice has been introduced by Toda [12] and studied extensively in the sequel. It is an FPU lattice, i.e. a Hamiltonian system of particles in one space dimension with nearest neighbor interaction. Models of this type have been studied by Fermi-Pasta-Ulam [FPU]. In numerical experiments they found recurrent features ...

متن کاملA Rational Flow for the Periodic Toda Lattice Equations
Dedicated to my long-time friend and colleague, Paul Fuhrmann, on the occasion of his 60 th birthday Abstract We show how a certain class of Hamiltonian systems give rise to diierential equations on spaces of matrices whose elements are rational functions. In particular, we reinterpret the results of Kac and van Moerbeke on the periodic Toda lattice in terms of such diierential equations and re...

We prove that the classical, non–periodic Toda lattice is super–integrable. In other words, we show that it possesses 2N−1 independent constants of motion, where N is the number of degrees of freedom. The main ingredient of the proof is the use of some special action–angle coordinates introduced by Moser to solve the equations of motion. Mathematics Subject Classification: 37K10, 37J35, 70H06
متن کاملSeparation of variables for the D n type periodic Toda lattice
We prove separation of variables for the most general (Dn type) periodic Toda lattice with 2 × 2 Lax matrix. It is achieved by finding proper normalisation for the corresponding Baker-Akhiezer function. Separation of variables for all other periodic Toda lattices associated with infinite series of root systems follows by taking appropriate limits.
