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
