    Abstract

    Using results from conformal field theory, we compute several universal amplitude ratios for the two-dimensional Ising model at criticality on a symmetric torus. These include the correlation-length ratio x* = limL → y ξ(L)/L and the first four magnetization moment ratios V2n = 〈.//2n〉/〈.//2n. As a corollary we get the first four renormalized 2n-point coupling constants for the massless theory on a symmetric torus. G*2n. We confirm these predictions by a high-precision Monte Carlo simulation.
