New Weierstrass elliptic function solutions of the N-coupled nonlinear Klein-Gordon equations

摘要

With the aid of symbolic computation, three families of new doubly periodic solutions are obtained for the N-coupled nonlinear Klein-Gordon equations in terms of the Weierstrass elliptic function. Moreover Jacobi elliptic function solutions and solitary wave solutions are also given as simple limits of doubly periodic solutions. (c) 2005 Elsevier Ltd. All rights reserved.
