If you have a question about this talk, please contact nobody. PDW - Emergent phenomena in nonlinear dispersive waves In this talk (joint work with A. Tovbis) I will discuss the spectra of finite-gap solutions for fNLS. We will show that the average intensity is equivalent to a problem in harmonic analysis of computing a specific Dirichlet energy associated with a domain in the upper half plane. We will also show that the Zakharov-Shabat spectra of finite gap solutions realize (local) minima of these Dirichlet energies amongst a well defined class of compact sets, a result that suggests a local stability property. Some elements of the proof will be discussed. This talk is part of the Isaac Newton Institute Seminar Series series. This talk is included in these lists:
