The behaviour of the mean Euler-Poincaré characteristic and mean Betti's numbers in the Ising model with arbitrary spin on as functions of the temperature is investigated through intensive Monte Carlo simulations. We also consider these quantities for each colour a in the state space SQ = {- Q, - Q + 2, ..., Q} of the model. We find that these topological invariants show a sharp transition at the critical point. © IOP Publishing Ltd and SISSA.
