Abstract:An extended F-expansion method is presented for finding periodic wave solutions of nonlinear evolution equations in mathematical physics, which can be thought of as a concentration of extended Jacobi elliptic function expansion method proposed recently.By using the homogeneous balance principle and the extended F-expansion, more periodic wave solutions expressed by Jacobi elliptic functions for a class of nonlinear Klein-Gordon equations are derived.
Keywords:Klein-Gordon equation  F-expansion method  Jacobi elliptic functions  Periodic wave solutions  Solitary wave solutions
