Symmetries and conservation laws of lattice Boussinesq equations
Pavlos Xenitidis, Frank Nijhoff
Sequences of canonical conservation laws and generalized symmetries for the lattice Boussinesq and the lattice modified Boussinesq systems are successively derived. The interpretat…

Symmetry algebra of discrete KdV equations and corresponding differential-difference equations of Volterra type
Pavlos Xenitidis
A sequence of canonical conservation laws for all the Adler-Bobenko-Suris equations is derived and is employed in the construction of a hierarchy of master symmetries for equations…
