摘要
借助于MATHEMATICA软件 ,将直接约化法推广并应用到 2 +1_维变系数广义Kadomtsev_Petviashvili(VCGKP)方程 ,获得了VCGKP方程的若干相似约化 ,其中包括PainleveⅠ型、PainleveⅡ型和PainleveⅣ型的约化·
With the aid of MATHEMATICA, the direct reduction method was extended and applied in 2+1_dimensional variable coefficient generalized Kadomtsev_Petviashvili equation(VCGKPE). As a result, several kinds of similarity reductions for VCGKPE are obtained which contain Painleve Ⅰ, Painleve Ⅱ and Painleve Ⅳ reductions.
