Linearization through symmetries for discrete equations [PDF]
Decio Levi, Christian ScimiternaWe show that one can define through the symmetry approach a procedure to check the linearizability of a difference equation via a point or a discrete Cole-Hopf transformation. If the equation is linearizable the symmetry provides the linearizing transformation. At the end we present few examples of applications for equations defined on four lattice points.View original: http://arxiv.org/abs/1302.0154
