摘要:

Let R(z) be an NCP map with buried components of degree d = degf ≥ 2 on the complex sphere ■, and HD denotes the Hausdorff dimension. In this paper we prove that if Rn→ R algebraically, and Rn and R topologically conjugate for all n >> 0, then Rn is an NCP map with buried components for all n >> 0, and for some C > 0,dH(J(R), J(Rn)) ≤ C(dist(R,Rn)1/d,where dH denotes the Hausdorff distance, and HD(J(Rn)) → HD(J(R)).In this paper we also prove that if the Julia set J(R) of an NCP map R(z) with buried components is locally connected, then any component Ji(R) is either a real-analytic curve or HD(Ji(R)) > 1.

Abstract:

Let R(z) be an NCP map with buried components of degree d = degf ≥ 2 on the complex sphere ■, and HD denotes the Hausdorff dimension. In this paper we prove that if Rn→ R algebraically, and Rn and R topologically conjugate for all n >> 0, then Rn is an NCP map with buried components for all n >> 0, and for some C > 0,dH(J(R),J(Rn)) ≤ C(dist(R, Rn)1/d,where dH denotes the Hausdorff distance, and HD(J(Rn)) → HD(J(R)).In this paper we also prove that if the Julia set J(R) of an NCP map R(z) with buried components is locally connected, then any component Ji(R) is either a real-analytic curve or HD(Ji(R)) > 1.
