Blow up phenomena and global existence for the nonlocal periodic Rotation-Camassa-Holm system
Pages: 1315 – 1335
Under consideration in the present paper is a mathematical model proposed as an equation of long-crested shallow-water waves propagating in one direction with the effect of Earth’s rotation. The system is called Rotation-Camassa-Holm system (RCH2). The local well-posedness of the periodic Cauchy problem is then established by the linear transport theory. Then, wave-breaking phenomena is investigated based on the method of characteristics and the Riccati-type differential inequality with two different kinds of methods. Finally, the wave-breaking data are illustrated and the existence of global solutions is obtained in detail for the periodic RCH2 system.
