Président: Robert P. LANGLANDS Rapporteurs Yves COLIN de VERDIERE, Marcus SLUPINSKI, Jean-Bernard ZUBERMy thesis generalizes the notion of criticality for the Ising model in two dimensions and defines a newtheory of discrete holomorphic functions on a cellular decomposition of a Riemann surface. The Ising model converges in the thermodynamical limit to a continuous conformal field theory, on square or triangular lattices near the critical temperature. We extend criticality to more general cellular decompositions. The key point is to double the decomposition, and to consider its dual. We define holomorphy with respect to a given metric by a straightforward discretization of the Cauchy-Riemmann equation. Classical theorems still hold and are ...
