报告摘要:
In this talk, we seek connections between the Sylvester equation and the Ablowitz-Kaup-Newell-Segur (AKNS) system. By the Sylvester equation KM?MK = r sT, we introduce master function S(i,j ) = sT Kj (I + M)?1Ki r. This function satisfies some recurrence relations. By imposing dispersion relations on r and s, we study the constructions of the AKNS system, where some AKNS type equations are investigated emphatically, including second-AKNS equation, second-modified AKNS equation, third-AKNS equation, third-modified AKNS equation and first negative-AKNS equation. The reductions of these equations to complex Korteweg-de Vries equation, real and complex modified Korteweg-de Vries type equations, nonlinear Schr?dinger type equations and sine-Gordon equation are discussed.
