Abstract
A decimation transformation preceded by a mean-field renormalisation group has been used to obtain the critical properties of various d-dimensional lattices. The method improves substantially both exponents and critical couplings even for small size clusters when compared with decimation and mean-field renormalisation group methods.Keywords
