Abstract

We introduce the concept of ω-lattice, constructed from τ functions of Painlevé systems, on which quad-equations of ABS (Adler-Bobenko-Suris) type appear. In particular, we consider the A5(1)- and A6(1)-surface q-Painlevé systems corresponding affine Weyl group symmetries are of (A2 + A1)(1) and (A1 + A1')(1)-types, respectively.
