We define infinitesimal contact transformations for ordinary difference schemes as transformations that depend on K + 1 lattice points (K >= 1) and can be integrated to form a local or global Lie group. We then prove that such contact transformations do not exist.

Abstract

We define infinitesimal contact transformations for ordinary difference schemes as transformations that depend on K + 1 lattice points (K >= 1) and can be integrated to form a local or global Lie group. We then prove that such contact transformations do not exist.
