Solitary wave solutions of the Phi-Four equation and the breaking soliton system by means of Jacobi elliptic sine-cosine expansion method

The goal of this study is twofold. The Jacobi elliptic expansion method is used to extract new solutions for the phi-four equation and the breaking soliton system. Special values of the Jacobi elliptic module and other involved parameters are chosen to produce solutions of soliton type and singular periodic solutions. The obtained solutions are verified and presented graphically.
