joigus Posted December 23, 2023 Share Posted December 23, 2023 Normalisation should come first. What is so suspicious about the motivation that you need an "actual motivation"? Isn't the fact that physical parameters should be expected to depend on the length/energy scale at which you observe them enough motivation?

MigL Posted January 4 Share Posted January 4 I don't know the mathematical motivation. The Physical motivation is the elimination of divergences in the perturbative corrections of Quantum Field Theory. Link to comment Share on other sites More sharing options...
