Limits of harmonic maps and crowned hyperbolic surfaces
Abstract
We consider harmonic diffeomorphisms to a fixed hyperbolic target , from a family of domain Riemann surfaces degenerating along a Teichm\"{u}ller ray. We use the work of Minsky to show that there is a limiting harmonic map from the conformal limit of the Teichm\"{u}ller ray, to a crowned hyperbolic surface. The target surface is the metric completion of the complement of a geodesic lamination on . The conformal limit is obtained by attaching half-planes and cylinders to the critical graph of the holomorphic quadratic differential determining the ray. As an application, we provide a new proof of the existence of harmonic maps from any punctured Riemann surface to a given crowned hyperbolic target of the same topological type.
