Discrete $Z^γ$: embedded circle patterns with the combinatorics of the square grid and discrete Painlevé equations
Abstract
A discrete analog of the holomorphic map $z^γ$ is studied. It is given by Schramm's circle pattern with the combinatorics of the square grid. It is shown that the corresponding circle patterns are embedded and described by special separatrix solutions of discrete Painlevé equations. Global properties of these solutions, as well as of the discrete $z^γ$, are established.
