Abstract: (Elsevier)
A renormalization group block-spin scheme for Z(2) gauge theory is constructed using a hamiltonian formulation. The renormalization group equations enable us to calculate the critical coupling and critical exponents both in 2 + 1 and 3 + 1 dimensions. The results compare favorably with those of the Ising model in a transverse field in the 2 + 1 case. In 3 + 1 dimensions the results turn out to satisfy the self-duality constraint. The critical exponents obtained are in agreement with the Migdal conjecture.- GAUGE FIELD THEORY: Z(2)
