Correlation-function identities for general planar Ising systems

A system of exact algebraic relations is derived for the spin correlation functions on any so-called “boundary set” of an Ising model on an arbitrary planar graph. One way of expressing these relations is to say that every higher-order correlation function is equal to a Pfaffian of the pair correlation function on the same set of boundary spins.
