Dimensional regularization is just high-level bullshit
-
This is about regularizing divergent sums, which is certainly well-defined in a certain sense. It has not much to do with dimensional regularization, however (afaik).

so the method of regulation is irrelevant because they’re all the same asymptotic expansion

I think my point is that it’s weird to even call dim reg a “regulator” because the way it’s implemented is completely unrelated to the “add a smooth regulator to a sum/integral) method this type of math uses. Something about analytically continuing in the dimensionality of your..
