We consider a class of quasi-linear, Hamiltonian Schrödinger equations on the d dimensional torus. We discuss the problem of existence and unicity of classical solutions of the Cauchy problem associated to the equation with initial conditions in the Sobolev space H^s, with s large. We also present results about the lifespan and stability of small solutions. The proofs of such results involves techniques of para-differential calculus combined with normal form theory.
