报告摘要：The discrete coupled nonlinear Schrodinger (DCNLS)  hierarchy associalted with a discrete 3*3 matrix spectral problem is derived,  which are composed of the positive and negative flows. Utilizing the  characteristic polynomial of Lax matrix for the DCNLS hierarchy, we introduce a  tragonal curve with three infinite points and three zero points, from which we  established the associated Baker-Akhiezer function and meromorphic  functions.
