Аннотация: We develop the spectral representation of propagator for n mixing fermion fields in case of Pparity violation. Solving of the eigenstate problem for inverse matrix propagator allows to build the system of orthogonal projectors and to represent the matrix propagator as a sum of poles with positive and negative energy. The procedure of multiplicative renormalization is investigated, the renormalization matrices are obtained in a closed form without using of pertubation theory.
