Resumen:
We extend a previously developed technique for computing spin - spin critical correlators in the two-dimensional (2D) Ising model, to the case of multiple correlations. This enables us to derive Kadanoff - Ceva's formula in a simple and elegant way. We also exploit a doubling procedure in order to evaluate the critical exponent of the polarization operator in the Baxter model. Thus we provide a rigorous proof of the relation between different exponents, in the path-integral framework.
