The closeness of localized structures between the Ablowitz-Ladik lattice and discrete nonlinear Schrödinger equations: Generalized AL and DNLS systems
Hennig D., Karachalios N.I., Cuevas-Maraver J. (2022)The Ablowitz-Ladik system, being one of the few integrable nonlinear lattices, admits a wide class of analytical solutions, ranging from exact spatially localized solitons to rational solutions in the form of the ... -
The closeness of the Ablowitz-Ladik lattice to the Discrete Nonlinear Schrödinger equation
Hennig D., Karachalios N.I., Cuevas-Maraver J. (2022)While the Ablowitz-Ladik lattice is integrable, the Discrete Nonlinear Schrödinger equation, which is more significant for physical applications, is not. We prove closeness of the solutions of both systems in the sense of ...
