Codice QDD182 Titolo Stable solitary waves with prescribed L2 mass for the cubic Schrodinger system with trapping potentials Data 2014-05-22 Autore/i Noris, B.; Tavares, H.; Verzini, G. Link Download full text Abstract For the cubic Schrodinger system with trapping potentials in RN, N <= 3, or in bounded domains, we investigate the existence and the orbital stability of standing waves having components with prescribed L2 mass provide a variational characterization of such solutions, which gives information on the stability through of a condition of Grillakis-Shatah-Strauss type. As an application, we show existence of conditionally orbitally stable solitary waves when: a) the masses are small, for almost every scattering lengths, and b) in the defocusing, weakly interacting case, for any masses.
