The renormalization group mapping in three dimensions

The construction of the quantitative RG mapping [SD89J starts from the perturbation expansion of W(u) evaluated to order uG or from the expansions for r (u) or 2 — l/i/(u) evaluated to order us. These expansions are only asymptotic, but they can be resumed, using the Borel method. Within [Pg.226]

Rigorous integration of the resulting flow equations (of. Sect. 11.4) yields [Pg.227]

Our final expression for the RG mapping therefore reads RG Mapping (d = 3) [Pg.228]

The nonuniversai constants sn can be expressed in terms of the starting value /o = /(A = 1) -as [Pg.228]
