摘要
设P(z)是d(≥2)次多项式,J是P(z)的Julia集,σ:∑n→∑n是n个符号的单边符号空间∑n上的转移自映射.本文证明了当p(z)的某m(1≤m≤d-1)个有穷临界点的轨道收敛于∞时,p|J拓扑半共轭于σ:∑(m+1)→∑(m+1),而当m=d-1时,p|J拓扑共轭于σ:∑d→∑d。
In this paper, the following results are proved.Let p(z)be a polynomial of degree d and J be the Julia set.Suppose the orbits of m (1≤m≤d-1)finite critical points of p(z)coverge to infinity.Then p|J is topologically semiconjugate to the one-sided shift on m + 1 symbols. In particular, when m = d-1, p|J is topologically conjugate to one-sided shift on d symbols.
