Abstract

Abstract:

In this article, the existence, uniqueness and regularities of the global generalized solution and global classical solution for the periodic boundary value problem and the Cauchy problem of the general cubic double dispersion equation
u_tt-u_xx-au_xxtt+bu_x⁴-du_xxt=f(u)_xx
are proved, and the sufficient conditions of blow-up of the solutions for the Cauchy problems in finite time are given.

Key words: The generalized cubic double dispersion equation, Cauchy problem, existence and uniqueness of global solution, nonexistence of global solution
