Abstract

The low-temperature series are calculated for the free energy, magnetization and susceptibility in the Q-state Potts model on the square lattice, using the improved algorithm of the finite lattice method. The series are obtained to the order of z41 for each of Q=5-50, and the result of their Padé type analysis is compared with those of the large-Q expansion and the Monte Carlo simulations.
