Abstract
The investigation of pure quantized Yang-Mills theories by means of ca usal perturbation theory is continued. We prove (re)normalizability an d study gauge invariance by introducing additional couplings between Y ang-Mills and ghost fields. Then, gauge invariance can be expressed by a large but finite set of identities between C-number distributions, analogous to the Ward-Takahashi identities. We work with free fields t hroughout, so that all expressions are mathematically well-defined.
