Query: Self-Dual Systems, their Symmetries and Reductions to the Bogoyavlensky
  Lattice   We recently introduced a class of ${\mathbb{Z}}_N$ graded discrete Lax pairs
and studied the associated discrete integrable systems (lattice equations). In
particular, we introduced a subclass, which we called "self-dual". In this
paper we discuss the continuous symmetries of these systems, their reductions
and the relation of the latter to the Bogoyavlensky equation.
