Title:  Topological characterization of rational maps with Siegel disks

Abstract:  We extend Thurston topological characterization theorem for PCF rational maps to a class of rational maps with a bounded type Siegel disk. This is the first result in generalizing Thurston theorem to geometrically infinite rational maps.
