RESUMO

This work describes a formal deduction of dynamics equations for the nÂvortex problem on a regular surface. Equations for the specic case in which the surface is parametrized by an isotermal coordinates system are presented. A rst order approximation is obtained for the dynamic of nÂvortex on a surface dieomorc to the sphere by a small radial perturbation
