Abstract:

I will present a result on the controllability of the gravity-capillary water wave system with arbitrary spatial dimensions. I will prove that, if $\omega$ is a domain of the free surface satisfying a geometric control condition, then by applying an exterior pressure on $\omega$, we can generate arbitrary shapes of the free surface and arbitrary vector fields of the fluid provided they are both sufficiently small. This result generalizes the work of Alazard, Baldi and Han-Kwan on the controllability of the gravity-capillary water wave system with two spatial dimensions.
