Two Classes Of Darboux Transformations Of(2+1)-dimensional KP Equations

In this paper, we study the Darboux transformation of the (2+1)-dimensional KP equation. First from a known spectral problem, we considered the two different forms of Darboux transformation. Then starting from the1-time, we get the N-times form for each type of Darboux transformation. Finally we can get the general expression of (2+1)-dimensional KP soliton equations using Darboux transformation, and several interesting figueres of the soltions are plottde.
