Inequality (7a) is immediate from Eq. (4a). Since cos{θ + id) … WebThe systematic approximation to the Migdal's recursion relation worked out in a previous publication is applied to a spin system withO(n) symmetry. Numerical results are obtained for the fixed point temperature in 2+∈ dimension and logarithmic corrections in 2 dimensions. these results are compared with those obtained using field theoretical …

WebJul 6, 1981 · We study the Migdal recursion relations and the reformulation due to Kadanoff for SU (2) and SU (3) lattice gauge theory, using analytic approximations for large and … WebWe study the Migdal-Kadanoff recursion relations for lattice gauge models with gauge groups SU ( N) or U ( N) in dimensions d <4. It is shown that the Gibbs factor of a plaquette with Wilson action is driven to 1 for all values of the “temperature” (coupling constant). WebThe results conform Migdal's scheme about the connection between four-dimensional gauge field and two-dimensional chiral system. And the recursion relation can be generalized to D dimensions gauge theories with chiral models in D-2 dimensions. fromis 9 album
