Near-integrability of periodic FPU-chains

Rink, Bob; Verhulst, Ferdinand - In: Physica A: Statistical Mechanics and its Applications 285 (2000) 3, pp. 467-482

-theory. This leads to the presence of many invariant tori on which the motion is quasi-periodic. Thus we explain the recurrence …

Renormalization group analysis of differential equations subject to slowly modulated perturbations

Paquette, Glenn C. - In: Physica A: Statistical Mechanics and its Applications 276 (2000) 1, pp. 122-163

The application of renormalization group (RG) theory to the asymptotic analysis of differential equations is considered. It is found that there is a class of small structural perturbations whose effects cannot be systematically treated using the Gell-Mann–Low RG approach applied in this...
