Abstract
The nonlinear Schrödinger equation models mixing phenomena such as modulational instability in fibers. I ts r egular b ehavior w as a ssociated t o Fermi-Pasta-Ulam-Tsingou recurrence. We rigorously compare their behaviors and clarify this analogy, set-tling a long-lasting debated problem.File in questo prodotto:
