Abstract:Thurston conjectured that hexagonal circle packings can be used to approximate the Riemann mapping. The corresponding convergence was proven by Rodin and Sullivan. He and Schramm showed that for hexagonal circle packings the convergence is C ∞ . Here the C ∞ -convergence is generalized to the case of non-hexagonal circle packings with bounded degree. Furthermore, the estimation of the convergence rate is obtained for arbitrary order derivatives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
