Hamiltonian formulation of string theory and multiloop amplitudes in the operator context,volution of any operator of the theory and, in particular, allows us to derive the equations of motion of the fundamental fields. Scattering amplitudes are defined as correlation functions of suitable vertex operators. The formalism lets one in general compute any correlation function. We compute co
