I can't believe why no one is answer my simple question. I know in power series, one expand the terms. I'm asking if the techniques in Renormalizaton Group can be applied to Finance or Biology problem, not just in QFT. If one knows the answer to this. Please let me know. Thanks.
Look at

to get a reasonably elementary explanation of renormalization and the renormalization group without any dirty tricks - is a simpler situation where everything can be understood explicitly.
