Secondly, we investigate the instability among patch solutions with a perturbed surface. To this end, we study the linearized system of a contour dynamics equation derived in [18] in the case where the support of the patch is axisymmetric and is described by spherical parametrization and show well-posedness of the linearized system. The actual version does not include the investigation of the eigenvalue and will be completed in the future.
