摘要：
The three-coupled Gross-Pitaevskii equation with a harmonic potential in a (2+1)-dimensional spin-1 Bose -Einstein condensate is studied in this paper. Using the Hirota bilinear method, the bright and dark soliton solutions of the system with attractive and repulsive interactions are obtained, and the amplitudes and velocities of those solitons are also given. In addition, we analyze the influence of harmonic potential on the dynamics of solitons and discuss the interaction between solitons through asymptotic analysis. As a result, we find that the amplitude and velocity of solitons are related to the harmonic potential, and the interaction between the two solitons is elastic.
