Abstract:
We study the Cauchy problem for a class of sixth order Boussinesq equations with the generalized source term and damping term. By using Galerkin approximations and potential well methods, we prove the existence of global weak solution. Furthermore, we talk about the condition of damped coefficient k and obtain the finite time blow up solution.
