Perturbation Expansion and N-th Order Fermi Golden Rule of the Nonlinear Schr\"odinger Equations
Abstract
In this paper we consider generalized nonlinear Schr\"odinger equations with external potentials. we compute the forth and the sixed order Fermi Golden Rules (FGR), conjectured in our previous papers, which is used in a study of the asymptotic dynamics of trapped solitons.
