Finite and infinite degree Thurston maps with extra marked points
Abstract
We investigate the family of marked Thurston maps that are defined everywhere on the topological sphere , potentially excluding at most countable closed set of essential singularities. We show that when an unmarked Thurston map is realized by a postsingularly finite holomorphic map, the marked Thurston map , where is the corresponding finite marked set, admits such a realization if and only if it has no degenerate Levy cycle. To obtain this result, we analyze the associated pullback map defined on the Teichm\"uller space and demonstrate that some of its iterates admit well-behaved invariant complex sub-manifolds within . By applying powerful machinery of one-dimensional complex dynamics and hyperbolic geometry, we gain a clear understanding of the behavior of the map restricted to the corresponding invariant subset of the Teichm\"uller space .
