I hear that in multiplicative renormalization,one only need to absorb all loop divergents on to
bare parameters(mass and coupling constant),so I don't understand why overlapping diagrams will ruin renormalization process in Dyson method(multiplicative renormalization method).Please teach me on this problem.
Please permit me send you my best wishes and gratitude.
