By using the reciprocal transformation between the modified short pulse (mSP) equation and the sine-Gordon (sG) equation, periodic solutions of the mSP equation are constructed and further used to recover solitary wave solutions and novel standing wave solutions. The obtained solutions include one-phase and two-phase periodic solutions, as well as one-cuspon, two-cuspon, and one-breather solutions.
With the aid of the reciprocal transformation between the modified short pulse (mSP) equation and the sine-Gordon (sG) equation, certain periodic solutions of the mSP equation are constructed. Both one-phase and two-phase periodic solutions are presented. Taking the proper limits of those periodic solutions, various solitary wave solutions such as one-cuspon, two-cuspon and one-breather solutions are recovered. In addition, three novel standing wave solutions for the mSP equation are obtained.
