Abstract

Let S be a closed surface of genus g greater than zero. In the present paper we study the topological-dynamical action of the mapping class group on the \Bbb Tn-character variety giving necessary and sufficient conditions for Mod(S)-orbits to be dense. As an application, such a characterisation provides a dynamical proof of the Kronecker's Theorem concerning inhomogeneous diophantine approximation.
