Revisiting the combinatorics of the 2D Ising model
Annales de l’Institut Henri Poincaré D, Tome 4 (2017) no. 3, pp. 309-385.

We provide a concise exposition with original proofs of combinatorial formulas for the 2D Ising model partition function, multi-point fermionic observables, spin and energy density correlations, for general graphs and interaction constants, using the language of Kac–Ward matrices. We also give a brief account of the relations between various alternative formalisms which have been used in the combinatorial study of the planar Ising model: dimers and Grassmann variables, spin and disorder operators, and, more recently, s-holomorphic observables. In addition, we point out that these formulas can be extended to the double-Ising model, de�fined as a pointwise product of two Ising spin con�gurations on the same discrete domain, coupled along the boundary.
