What is the difference between the concept of scale in the SM QFTs and the scale concept in geometry?
In other words, QFT is a scale-dependent theory that is living on a scale-invariant space(either R4 or M4, related by Wick rotations). Mathematically scale-invariance and scale-dependence appear as incompatible, are they congenial in QFT? and if so how is that achieved?
