Transcendental Julia sets of minimal Hausdorff dimension

Abstract We show the existence of transcendental entire functions f: C C with Hausdorff-dimension 1 Julia sets, such that every Fatou component of f has infinite inner connectivity. We also show that there exist singleton complementary components of any Fatou component of f, answering a question of Rippon and Stallard Eremenko points and the structure of the escaping set. Trans. Amer. Math. Soc. 372 (5) (2019), 3083–3111. Our proof relies on a quasiconformal-surgery approach developed by Burkart and Lazebnik Interpolation of power mappings. Rev. Mat.
