General Jacobian elliptic function expansion method and its applications

摘要

An extended Jacobian elliptic function expansion method is presented and successfully applied to the nonlinear Schr(o)dinger (NLS) equation and Zakharov equation. We obtain some new solutions besides Fu et al's results. The results show that our method is more powerful to construct Jacobian elliptic function and can be applied to othernonlinear physics systems.
