摘要：In this talk, a spatial discretization of the integrable deformed mKdV equation with nonholonomic constraint is investigated. The integrability of the discrete model is confirmed by showing the existence of Lax pair, Darboux transformations and multi-solitons. The theory of the system including Lax pair, Darboux transformations and explicit solutions systematically yields their continuous counterparts in the continuous limit. Finally, under the reduction, the deformed model gives an integrable discretization of the combined mKdV and Sine-Gorden equation.
