英文摘要：

The reduction method by the KP hierarchy Baofeng Feng School of Mathematical and Statistical Sciences University of Texas Rio Grande Valley Edinburg,TX, 78539-2999 U.S.A. ABSTRACT In this talk, we will firstly outline Hirota’s bilinear method and the Kadomtsev-Petviashvili (KP) theory for integrable systems, i.e., a class of exactly solvable partial differential equations (PDEs). We will reveal the unified algebraic structure underlying the continuous and discrete integrable systems via showing how to generate Hirota’s bilinear equations for the whole KP hierarchy and how to prove their general solutions, the so－called tau functions. Then, we will show how the general solitons to several typical soliton equations such as the KdV equation and the NLS equation can be obtained via the reduction method of the KP hierarchy.
