Numerical analysis of the one-mode solutions in the Fermi-Pasta-Ulam system
Alessandro Cafarella, Mario Leo, Rosario Antonio Leo
The stability of the one-mode nonlinear solutions of the Fermi-Pasta-Ulam - system is numerically investigated. No external perturbation is considered for the one-mode exact an…

Exact Solutions for Wave Propagation in Birefringent Optical Fibers
E. Alfinito, M. Leo, R. A. Leo +2
We carry out a group-theoretical study of the pair of nonlinear Schrödinger equations describing the propagation of waves in nonlinear birefringent optical fibers. We exploit the s…
