Integrable equations of the infinite nonlinear Schrödinger equation hierarchy with time variable coefficients

Kedziora, David; Ankiewicz, Adrian; Chowdury, Atiqur; Akhmediev, Nail


We present an infinite nonlinear Schrödinger equation hierarchy of integrable equations, together with the recurrence relations defining it. To demonstrate integrability, we present the Lax pairs for the whole hierarchy, specify its Darboux transformations and provide several examples of solutions. These resulting wavefunctions are given in exact analytical form. We then show that the Lax pair and Darboux transformation formalisms still apply in this scheme when the coefficients in the...[Show more]
