Geometrical aspects of the Z-invariant Ising model
Ruben Costa-Santos
We discuss a geometrical interpretation of the Z-invariant Ising model in terms of isoradial embeddings of planar lattices. The Z-invariant Ising model can be defined on an arbitra…

The Ising model on curved lattices
Ruben Costa-Santos
We review recent results concerning finite size corrections to the Ising model free energy on lattices with non-trivial topology and curvature. From conformal field theory consider…
