Symmetries and Special Solutions of Reductions of the Lattice Potential KdV Equation ?


We identify a periodic reduction of the non-autonomous lattice potential Korteweg–de Vries equation with the additive discrete Painlevé equation with E (1) 6 symmetry. We present a description of a set of symmetries of the reduced equations and their relations to the symmetries of the discrete Painlevé equation. Finally, we exploit the simple symmetric form… (More)
