über eine natürliche Regularisierung von Zweipunktfunktionen

A field belonging to a Heisenberg type particle equation with operators derived from the elements of a commutator ring is quantized according to Fermi statistics. The resulting anticommutator is shown to be more general than the Lehmann-Källén type. It contains a density function for every mass value, that may be used to regularize, with the help of an indefinite metric, theδ-function without implications for the mass spectrum.
