dc.descriptionField theory at nonvanishing temperature beyond perturbation theory is discussed for the $N$-component $O(N)$-symmetric scalar theory. We compute the effective potential directly in three dimensions using an exact evolution equation for an effective action with an infrared cutoff. A suitable truncation is solved numerically. We obtain a detailed quantitative picture of the scaling form of the equation of state in the vicinity of the critical temperature of a second order phase transition.
