Critical exponents predicted by grouping of Feynman diagrams in \(\varphi^4\) model (English)
0 references
The aim of the reviewed article is to give a critical analysis of the conventional approach in calculation of critical exponents based on the perturbative renormalization group theory and to propose a new method which provides results consistent with the known exact solutions. Different perturbation theory treatments of the Ginzburg-Landau phase transition model are discussed.
