چکیده
We prove that the canonical Thurston obstruction for a sub-hyperbolic semi-rational branched covering exists if the branched covering is not CLH-equivalent to a rational map.

Geometrization of Sub-hyperbolic Semi-rational Branched Coverings
Given a sub-hyperbolic semi-rational branched covering which is not CLH-equivalent a rational map, it must have the non-empty canonical Thurston obstruction. By using this canonical Thurston obstruction, we decompose this dynamical system in this paper into several sub-dynamical systems. Each of these subdynamical systems is either a post-critically finite type branched covering or a sub-hyperb...
متن کاملThe Thurston Type Theorem for Branched Coverings of Two-Sphere
I give a survey about a program which intends to find topological characterizations of a rational map and then use them to study the rigidity problem for rational maps. Thurston started this program by considering critically finite branched coverings and gave a necessary and sufficient combinatorial condition for a critically finite rational maps among all critically finite branched coverings. ...
متن کاملCombinatorial characterization of sub-hyperbolic rational maps
In 1980’s, Thurston established a combinatorial characterization for post-critically finite rational maps among post-critically finite branched coverings of the two sphere to itself. A completed proof was written by Douady and Hubbard in their paper [A. Douady, J.H. Hubbard, A proof of Thurston’s topological characterization of rational functions, Acta Math. 171 (1993) 263–297]. This criterion ...
متن کاملOn geometrically finite branched coverings∗ II. Realization of rational maps†
Following the first part of our research, we prove in this paper that a sub-hyperbolic semi-rational map with infinite post-critical set is combinatorially and locally holomorphically equivalent to a rational map if and only if it has no Thurston obstruction. Moreover, the rational map is unique up to holomorphic conjugation.
متن کاملOn geometrically finite branched covering∗ III. A direct proof of CJS’s theorem†
We studied the rational realization problem for sub-hyperbolic semi-rational branched coverings. By using the shielding ring lemma, we are able to give a direct proof of CJS’s Theorem following the lines of the proof of Thurston’s Theorem given in the paper of Douady-Hubbard.
