摘要: 该文给出一个严格的极限过程,从修正KdV方程的Hirota的2N-孤子解出发,得到N-双重极点解,并且给出后者的一个简洁表示.这种极限过程具有普遍性,可以应用到其他具有Hirota形式多孤子解的非线性发展方程.

关键词: 2N-孤子解, N-双重极点解, 极限过程, 双线性方程, 修正KdV方程

Abstract: This paper describes an exact limit procedure by which a simple formula for the N-doublepole solution to the modified KdV equation is derived from its 2N-soliton solution in the Hirota’s form. This procedure is general and can be applied to other nonlinear evolution equations with multi-soliton solutions in the Hirota's form.

Key words: 2N-soliton solution, bilinear equation, limit procedure, N-doublepole solution, modified KdV equation
