I will discuss some recent results in collaboration with Emanuele Haus and Marcel Guardia. I will consider the analytic non-linear Schrodinger equation on a two-dimensional torus and exhibit orbits whose Sobolev norms grow with time. The main point is to make use of an accurate combinatorial analysis in order to reduce to a sufficiently simple toy model, similar in many ways to the one used for the case of the cubic NLS.
