摘要: 本文研究了若谱按规律(n1≤m1)变化,且A1,B1,C1均为λ的正负幂多项式时,AKNS特征值问题q(x,t),r(x,t)的发展方程的一般结构,其中q,r在无穷远处不附加任何条件.Abstract: In this paper, we study the general structure of evolution equations of the AKNS eigenvalue problem q(x,t), r(x,t) with the spectrum varying as and A1,B1,C1 are all positive or negative power polynomials of where q, r are not limited with any additional conditions at infinity.
