We will discuss the construction of renormalization operators acting on
vector fields and their application to dynamical systems problems. We will
be mainly interested on the stability of diophantine invariant tori in
Hamiltonian flows close to integrable and related systems. The
renormalization relies fundamentally on a strongly convergent
multidimensional continued fraction expansion based in the geodesic flow of
the homogeneous space of unimodular lattices, which we will discuss.
