Abstract: This talk will introduce the new decay estimates for a dissipative-dispersive linear semigroup. Applying the decay estimates to the Boussinesq equation, we establish some results about the global wellposedness, decay estimates, inviscid limit of small solutions. Moreover, with the help of large dispersive coefficient, we establish the almost global wellposedness of large solutions and time periodic solutions for large external force.
