Abstract
Within the real space renormalisation group framework, the authors discuss the critical point and exponent nu of the Potts ferromagnet in b-sized Migdal-Kadanoff-like hierarchical lattices, Both b to infinity and b to 1 limits are exhibited. The important discrepancies that might exist between the exact results for d-dimensional hierarchical lattices and d-dimensional Bravais lattices are illustrated.Keywords
