The Improved F-expansion Method And Its Application To Some Soliton Equations

In this papcr,wc study the Zakharov-Kuznetsovequation, modified Zakharov-Kuznetsov equation. Gardner-KP equation, fifth-order Sawada-Kotera equation and coupled Ito equation by the homogeneous balance method and the extended F-expansion method by which solutions can be constructed uniformly and symbolicly. With the help of Maple, we can obtain some new exact solutions.
