| Abstract: | We study how to set up systematic summation rules that could permit us to interpret the divergent expressions arising in the perturbation theory of :P( ):d when one does not allow any renormalization besides the usual coupling constants, mass and wave function renormalizations.Supported in part by NSF grant PHY-8342570.
