The critical properties of the 2D Ising and 3-state Potts models are
investigated using Monte Carlo simulations. Special interest is given to
measurement of 3-point correlation functions and associated universal objects,
i.e. structure constants. The results agree well with predictions coming from
conformal field theory confirming, for these examples, the correctness of the
Coulomb gas formalism and the bootstrap method.Comment: 11 pages, 6 Postscript figures, uses Revte
