There, the operation of projecting out higher energies is replaced with a unitary transformation. A somewhat reduced version of this approach, widely used for non-relativistic systems, is known as Similarity Renormalization Group, while for relativistic systems it is known as Renormalization Group Procedure for Effective Particles. | |

| Jun 25, 2020 at 15:49 | comment | added | Abdelmalek Abdesselam | Just a remark. At this point in time, a general rigorous theory might be too much to ask. One has a general philosophy/nonrigorous theory/loose set of methods and guidelines/...but within the scope of this philosophy there are examples treated rigorously. The general idea is very simple and surprisingly powerful when it can be implemented rigorously. See mathoverflow.net/questions/363119/… | |

| Jun 25, 2020 at 9:29 | comment | added | Igor Khavkine | Just a comment. "Renormalization" means different things to different people. It sounds like you mean "Wilsonian renormalization," unless there's some more specific label that you can attach to it. Perhaps that terminology should be reflected in your question. | |
