Action as an invariant of Bäcklund transformations for Lagrangian systems
V. G. Marikhin Landau Institute for Theoretical Physics, RAS, Moscow,

Abstract:
We construct a general theory of Bäcklund transformations for Lagrangian systems under the condition that the action is preserved by these transformations. We discuss the known Bäcklund transformations for classical soliton equations from the standpoint of this approach and obtain a new Bäcklund transformation for the Tzitzéica equation.
Keywords:
integrable system, canonical transformation.
