Binary Darboux transformation of time-discrete generalized lattice Heisenberg magnet model

The standard binary Darboux transformation is used to find the solutions of time-discrete generalized lattice Heisenberg magnet (GLHM) model. We compute quasi-Grammian multisoliton solutions by iterating the binary Darboux transformation and the explicit soliton solutions for the SU(2) case are also obtained. (C) 2019 Elsevier Ltd.
