Abstract

In this paper we investigate the motion of a rigid ball in anincompressible perfect fluid occupying ${\mathbb R}^2$ .We prove the global in time existence and the uniqueness ofthe classical solution for this fluid-structure problem. The proof reliesmainly on weighted estimates for the vorticity associated withthe strong solution of a fluid-structure problemobtained by incorporating some dissipation.
