The symmetry approach to integrability: recent advances
Rafael Hernández Heredero, Vladimir Sokolov
We provide a concise introduction to the symmetry approach to integrability. Some results on integrable evolution and systems of evolution equations are reviewed. Quasi-local recur…

Multiscale expansion and integrability properties of the lattice potential KdV equation
Rafael Hernandez Heredero, Decio Levi, Matteo Petrera +1
We apply the discrete multiscale expansion to the Lax pair and to the first few symmetries of the lattice potential Korteweg-de Vries equation. From these calculations we show that…
