摘要:

该文基于双Bell多项式与Hirota双线性算子之间的关系, 研究了一类(1+1)维变系数复方程的可积性. 首先通过适当的变换, 构造出方程的双线性表达式、双线性Bäcklund变换, 又通过Hopf-Cole变 换得到方程的Lax对, 从而证明该方程具有Lax可积性.

关键词: (1+1)维变系数复方程, Bell多项式, Hirota双线性形式, B?cklund变换, Lax对

Abstract:

In this paper, we study the integrability of a (1+1)-dimensional variable coefficient complex equation based on the relationship between multi-dimensional binary bell polynomial and Hirota bilinear operator. Firstly, the bilinear form and bilinear Bäcklund transformation of the equation are constructed by appropriate transformation. Then the lax pair is obtained by Hopf-Cole transformation, which proves that the equation is Lax integrable.

Key words: (1+1)-dimensional variable coefficient complex equation, Bell polynomials, Hirota bilinear form, B?cklund transformation, Lax pair
