摘要:

In this paper, we study a differential-difference equation associated with dis-crete 3 ×3 matrix spectral problem. Based on gauge transformation of the spectral problm, Darboux transformation of the differential-difference equation is given. In order to solve the differential-difference equation, a systematic algebraic algorithm is given. As an appli-cation, explicit soliton solutions of the differential-difference equation are given.

关键词: Darboux transformation, solitons, explicit solution, Lax-pair, differential-difference equation
