Existence and uniqueness of global solutions to a class of Boussinesq type equations. (Chinese. English summary) Zbl 1249.35057

Summary: In this paper, the existence and uniqueness of global generalized solutions and global classical solutions to the Cauchy problem for a class of Boussinesq type equations of sixth order are proved. Some sufficient conditions of blow up of solutions to this Cauchy problem in finite time are also given.
