摘要:

通过定义平移算子和差分算子,并利用Lax配对的方法,找到了KP差分 -微分方程组的正确形式.定义了差分指数函数.借助穿衣算子法,得到了KP差分 -微分方程组的精确解析解.还讨论了KP差分 -微分方程组及其解的展开形式.

关键词: KP差分-微分方程组, 精确解析解, 差分指数函数

Abstract:

Throug h defining t ranslation operator and difference operator and using method of Lax pair, the co rrect form of the system of KP dif ference/ differential equations has been found out.The differenCeexponential function has been defined.By means of the dressing operator method, the ex act analysis solut ions of KP dif ference/ differential equat ions have been obtained.The expansion forms of KP difference/ differential equatio ns and their solutio ns have been discussed.

Key words: KP difference/dif ferent ial equations, exact analysis solution, differenCeexponential function
