Renormalization group method and canonical perturbation theory
Yoshiyuki Y. Yamaguchi, Yasusada Nambu
Renormalization group method is one of the most powerful tool to obtain approximate solutions to differential equations. We apply the renormalization group method to Hamiltonian sy…

Canonical structure of renormalization group equations and separability of Hamiltonian systems
Yoshiyuki Y. Yamaguchi, Yasusada Nambu
We investigate perturbed Hamiltonian systems with two degrees of freedom by renormalization group method, which derives a reduced equation called renormalization group equation (RG…

Renormalization group equations and integrability in Hamiltonian systems
Yoshiyuki Y. Yamaguchi, Yasusada Nambu
We investigate Hamiltonian systems with two degrees of freedom by using renormalization group method. We show that the original Hamiltonian systems and the renormalization group eq…
