Classification of discrete equations linearizable by point
transformation on a square lattice    [PDF]

Christian Scimiterna, Decio Levi

We provide a complete set of linearizability conditions for nonlinear partial difference equations de- fined on four points and, using them, we classify all linearizable multilinear partial difference equations defined on four points up to a Mobious transformation
