Resumo
We regularize the heat-kernel expansion of propagators in the presence of background fields. This leads to a renormalized perturbation series which is gauge-invariant and supersymmetric with respect to background variations. This procedure permits isolation of singularities in the computation of the effective action, obeying the above symmetries. © 1986.
