Holomorphic spinor observables in the critical Ising model. (English) Zbl 1277.82010

A problem of importance about the Ising model is the rigorous proof of the conformal covariance of spin correlations in the scaling limit. In the present paper one introduces the concept of spinor holomorphic observables to deal with this question, and one proves the convergence of ratios of spin correlations corresponding to various boundary conditions to conformally invariant limits.
