摘要
从新的视角考虑Hirota双线性变换,建立了Hirota-Satsuma方程与其双线性化方程之间的局部等价性。提出了双线性化Hirota-Satsuma方程的由二阶微分方程加上适当的初值条件所定义的新型B覿cklund变换,并通过该变换从Hirota-Satsuma方程的种子解构造出其双线性化方程新的精确解。
By considering the Hirota bilinear transformation from a new point of view,the local equivalence between the Hirota-Satsuma equation and its bilinear equation is established.A new type of B?cklund transformation,which is defined by a second-order ODE along with the appropriate initial values,is presented to new exact solutions for the bilinear Hirota-Satsuma equation from the seed solutions of original Hirota-Satsuma equation.
