摘要：

A new method to describe the dynamics of constant vorticity domains on the plane is proposed. The parameters of conformal mappings of the standard domain onto those latter are the new variables and a dynamical equation for their evolution is given. A perturbation theory around a basic elliptic shape of the vortex is formulated within this framework. As an illustration, the classical linear stability results for Love modes are reproduced.
