Tropical limit of complex dynamical systems Shishikura, Mitsuhiro
Complex rational maps induce rich and interesting dynamics on the Riemann sphere. We consider what happens to the dynamics when a rational map tends to the boundary of moduli space, i.e. tends to a lower degree map. A typical example is given by a stretching quasiconformal deformation of Fatou sets. In this case, the limit can be described a piecewise linear map on a tree. We discuss an inverse problem and related questions on quasiconformal deformation of annuli.
