Confirming Brennan's conjecture numerically on a counterexample to Thurston's $K=2$ conjecture

Abstract

It was shown by Bishop that if Thurston's $K = 2$ conjecture holds for some planar domain, then Brennan's conjecture holds for the Riemann map of that domain as well. In this paper we show numerically that the original counterexample to Thurston's $K=2$ conjecture given by Epstein, Marden and Markovi\'{c} is not a counterexample to Brennan's conjecture.
