- Descripción
- A generalization of a simple-majority rule model is presented. The system, say a d-dimensional hypercubic checkerboard, whose elements are coloured with one out of q colours with probabilities <math>p_1, p_2, ..., p_q\,\!</math>, presents a continuous phase, transition. Using a real space renormalization group (RG) approach, we establish the phase diagram as well as the correlation length critical exponent <math>\nu\,\!</math>. The various types of convergence of the RG numerical values for <math>\nu\,\!</math> towards the (presumably) exact answer are analysed in connection with finite size scalings.
