Abstract

We continue our series devoted, after references \citeCM24D1 and \citeCM243, at proving the asymptotic stability of ground states of the pure power Nonlinear Schrödinger equation on the line. Here we assume some results on the spectrum of the linearization obtained computationally by Chang et al. \citeChang and then we explore the equation for exponents p≤ 2 sufficiently close to 2. The ensuing loss of regularity of the nonlinearity requires new arguments.
