The Migdal renormalization group(MRG) procedure is applied to the finite temperature SU(2) lattice gauge theory.With its effective action form in terms of the Polyakov Zoop we an-alyse the strong and weak coupling approximations of the evolution of renormalized couplings.The distribution of renormalization group trajectory is obtained and the critical coupling is measured. |
