Abstract: Non-point invertible transformations are completely described for difference equations on the quad-graph and for their differential-difference analogues. As an illustration, these transformations are used to construct new examples of integrable equations and autotransformations of the Hietarinta equation.
Keywords: non-point transformation; Darboux integrability; discrete Liouville equation; higher symmetry.
