Exponential Asymptotics for Translational Modes in the Discrete Nonlinear Schr{ö}dinger Model

C. J. Lustri, P. G. Kevrekidis, S. J. Chapman

In the present work, we revisit the topic of translational eigenmodes in discrete models. We focus on the prototypical example of the discrete nonlinear Schr{ö}dinger equation, alt…
