Gradient flows for β functions via multi-scale renormalization group equations

HIGHLIGHTS

• who: Ulrich Ellwangera from the Laboratoire de Physique Théorique, UMR, CNRS, UnivParis-Sud, UnivParis-Saclay, Orsay, France have published the article: Gradient flows for β functions via multi-scale renormalization group equations, in the Journal: Eur. Phys. J. C (2019) 79:198 of /2019/
• what: It is the aim of this paper to show that the concept of different scales τi leads naturally to the definition of a gradient flow ηab (g)βb (g)= ∂ (g). ∂ga

SUMMARY

Originally multi-scale renormalization group (RG) flows were introduced to deal with physical problems . . .
