摘要: In this talk, we will introduce the dispersion in the damped Boussinesq equation and utilize the effect of dispersion to obtain the global well-posedness and asymptotic behavior, furthermore, inviscid limit for the damped Boussinesq equation. On one hand, the results show, with the dispersion and dissipation taken into account simultaneously, we get the better decay rate than that got only by the dissipation. Actually, the decay rates will plus with each other to a certain extent in which the one decay rate comes from dissipation and the other decay rate comes from dispersion. On the other hand, the results show when the dissipation vanishes, the solutions will converge strongly to the solution of associated to the Boussinesq equation which is a pure dispersive equation.
