In this paper, we consider an initial-boundary value problem for the following generalized Boussinesq water equation defined in a unit ball
The existence of mild solutions is established in the space where κ <5/2, and the solutions are constructed in the form of series of the small parameter present in the initial conditions. For −1/2 < κ < 5/2, the uniqueness is proved. In addition, the long-time asymptotics is obtained in explicit form.
