I have split off Stückelberg-Petermann renormalization group from main theorem of perturbative renormalization, just so as to record references.
Both entries remain stubs for the time being (will get to filling in details soon.)

I have phrased this with no renormalization condition assumed,
Here I was wrong. One needs one renormalization condition, namely “field independence” of the S-matrix/time-ordered products (here). This is because one needs this axiom on the vertex redefinitions in order for their “local additivity” to follow (this prop., I have expanded the proof to clarify this) and so then for the difference of two renormalization schemes to come from such a vertex redefinition, they need to be “field-independent” themselves.
I have fixed this.
