%X Dispersion relations for pion production in pion-nucleon colHssions are discussed. The scattering amplitude is written in a form, in which the operators of nucleon field are extracted from the state vectors of initial and final state. The kinematies and symmetry, properties are worked out in detail and the contribution of bound state is evaluated.
