报告摘要:
In this talk, we investigate the single-component and multi-component AB system, respectively, that appears in geophysical fluid dynamics. We construct bright-dark soliton solutions of the systems using the Hirota’s bilinear method and reduction technique. For the single-component AB system, N-bright soliton solutions to the focusing and N-dark soliton solutions to the defocusing AB system are provided
respectively. For the two-component AB system, we obtain asymptotic behaviours of two-soliton solution and prove that the interactions between two bright and two dark solitons are elastic. Under various parameter conditions, the oblique interactions and bound states of solitons are analyzed in detail. By use of the Pfaffian technique, we present N-bright and N−dark soliton solutions of the two- and multicomponent AB system.
