Abstract

In this letter, we introduced an integrable discrete coupled nonlinear Schrödinger equation with branched dispersion (dcNLSBD) and constructed its discrete

N

-fold Darboux transformation (DT). We studied several types of exact solutions for this equation with the aid of DT and investigated dynamics of the exact solutions.
