摘要：
A spherical Kadomtsev-Petviashvili (SKP) equation for dust acoustic or ion-acoustic waves is studied.Sim-ilarity reductions of the SKP equation are obtained with the one-parameter (ε) Lie group of infinitesimal transformationsand Clarkson-Kruskal direct method.The SKP equation is also solved with a generalized tanh function method.
