Abstract
Starting from field equations, asymptotic condition, Wightman functions and using a mathematically correct definition ofT-products, a general scheme is developed to yield a divergence-free formulation of quantum field theory. Propagators, BetheSalpeter amplitudes, scattering matrix elements, sum rules and equal time commutation relations are discussed.
