How can two different regularization schemes give the same physical results?(adsbygoogle = window.adsbygoogle || []).push({});

This seems unbelievable.

If you impose the same renormalization conditions, then in all regularization schemes, the cutoff, or dimension, or the heavy masses get absorbed into constants in such a way that the leftover finite piece is the same?

Is there a proof of this?
