Affine Weyl group symmetry of the discrete power function

Abstract:
In this talk, we show that the discrete power function associated with circle patterns of Schramm type can be obtained from a space-filling cubic lattice, each cube has CAC property, and its affine Weyl group symmetry. Moreover, we show that this cubic lattice and its symmetry are derived form the affine Weyl group symmetry of the sixth Painlevé equation.
