Description

Block-spin renormalization group transformation is used at the weak coupling regime to find an improved action. MC calculations show that for this action scaling sets in at small lattice correlation length (xiapprox.=2.5). The results are compared with the results obtained using the Symanzik improved and the standard model. (orig.)
