Five-loop renormalization-group expansions for two-dimensional Euclidean λϕ^4 theory
E. V. Orlov, A. I. Sokolov
The renormalization-group functions of the two-dimensional n-vector λϕ^4 model are calculated in the five-loop approximation. Perturbative series for the β-function and critical ex…

Universal effective action for O(n)-symmetric λϕ^4 model from renormalization group
A. I. Sokolov, E. V. Orlov, V. A. Ul'kov +1
The RG expansions for renormalized coupling constants g_6 and g_8 of the 3D n-vector model are calculated in the 4-loop and 3-loop approximations respectively. Resummation of the R…
