%0 Journal Article %T Thurston type Theorem for sub-hyperbolic rational maps %A Gaofei Zhang %A Yunping Jiang %J Mathematics %D 2008 %I arXiv %X In 1980's, Thurston established a combinatorial characterization for post-critically finite rational maps. This criterion was then extended by Cui, Jiang, and Sullivan to sub-hyperbolic rational maps. The goal of this paper is to present a new but simpler proof of this result by adapting the argument in the proof of Thurston's Theorem. %U http://arxiv.org/abs/0811.3042v2
