Title: Scattering below the ground state for the radial focusing NLS
Speaker: Jason Murphy, UCLA
Abstract: We consider scattering below the ground state for the radial cubic focusing NLS in three dimensions. Holmer and Roudenko originally proved this via concentration compactness and a localized virial estimate. We present a simplified proof that avoids the use of concentration compactness, relying instead on the radial Sobolev embedding and a virial/Morawetz estimate. This is joint work with Benjamin Dodson.
