Asymptotic symmetries of difference equations on a lattice / G. Gaeta, D. Levi, R. Mancinelli. - In: JOURNAL OF NONLINEAR MATHEMATICAL PHYSICS. - ISSN 1402-9251. - 12:suppl. 2(2005), pp. 137-146.
Abstract:
It is known that many equations of interest in Mathematical Physics display solutions
which are only asymptotically invariant under transformations (e.g. scaling and/or
translations) which are not symmetries of the considered equation. In this note we
extend the approach to asymptotic symmetries for the analysis of PDEs, to the case
of difference equations.
