On the Integrability of the Discrete Nonlinear Schroedinger Equation
Decio Levi, Matteo Petrera, Christian Scimiterna
In this letter we present an analytic evidence of the non-integrability of the discrete nonlinear Schroedinger equation, a well-known discrete evolution equation which has been obt…

The lattice Schwarzian KdV equation and its symmetries
Decio Levi, Matteo Petrera, Christian Scimiterna
In this paper we present a set of results on the symmetries of the lattice Schwarzian Korteweg-de Vries (lSKdV) equation. We construct the Lie point symmetries and, using its assoc…
