| Abstract: | The φ34 model at finite temperature is simulated on the lattice. For fixed Nt we compute the transition line for Ns → ∞ by means of finite size scaling techniques. The crossings of a renormalization group trajectory with the transition lines of increasing Nt give a well-defined limit for the critical temperature in the continuum. By considering different RG trajectories, we compute Tc/g as a function of the renormalized parameters. |
