On the susceptibility of the generalised square lattice Ising model
Héctor Giacomini
An exact functional relation is found for the susceptibility of the generalised square lattice Ising model. This result contains, as a particular case, a Fisher relation between the susceptibilities of the triangular and honeycomb lattices models. It is also shown that the closed-form expression for the susceptibility of the generalised square lattice, proposed by Syozi and Naya (1960), satisfies the functional relation presented in this letter.
