Tiivistelmä

We study the motion of charged liquid drop in three dimensions where the equations of motions are given by
the Euler equations with free boundary with an electric field. This is a well-known problem in physics going back to the famous work by Rayleigh. Due to experiments and numerical simulations one may expect the charged drop to form conicalsingularities called Taylor cones, which we interpret as singularities of the flow. In this paper, we study the well-posednessof the problem and regularity of the solution. Our main theorem is a criterion which roughly states that if the flow remains C1,α-regular in shape and the velocity remains Lipschitz-continuous, then the flow remains smooth, i.e., C∞ in time and space, assuming that the initial data is smooth. Our main focus is on the regularity of the shape of the drop. Indeed, due to the appearance of Taylor cones, which are singularities with Lipschitz-regularity, we expect the C1,α-regularity assumption to be optimal. We also quantify the C∞-regularity via high order energy estimates which, in particular, impliesthe well-posedness of the problem.
