Abstract

We formulate the problem of determining the Hausdorf dimension, df, of the Apollonian packing of circles as an eigenvalue problem of a linear integral equation. We show that solving a finite-dimensional approximation to this infinite-order matrix equation and extrapolating the results provides a fast algorithm for obtaining high-precision numerical estimates for df. We find that df=1.305 686 729(10). This is consistent with the rigorously known bounds on df, and improves the precision of the existing estimate by three orders of magnitude.
