Reflection groups and discrete integrable systems

Abstract: Abstract. We present a method of constructing discrete integrable systems with crystallographic reflection group (Weyl) symmetries, thus clarifying the relationship between different discrete integrable systems in terms of their symmetry groups. Discrete integrable systems are associated with space-filling polytopes arise from the geometric representation of the Weyl groups in the n-dimensional real Euclidean space R n . The "multi-dimensional consistency" property of the discrete integrable system is shown to… Show more

“…There are close relations, cf. [32,42], between non-autonomous ABS lattice equations and discrete Painlevé equations exploing the affine Weyl group. A particular example is provided by a non-autonomous version of the lpmKdV equation (2.22) which can be reduced to a q-Painlevé III equation, by performing a periodic reduction.…”
