Abstract
Let X be a closed hyperbolic surface and λ, η be weighted geodesic multicurves which are short on X. We show that the iterated grafting along λ and η is close in the Teichmüller metric to grafting along a single multicurve which can be given explicitly in terms of λ and η. Using this result, we study the holonomy lifts gr λ ρ X,λ of Teichmüller geodesics ρ X,λ for integral laminations λ and show that all of them have bounded Teichmüller distance to the geodesic ρ X,λ. We obtain analogous results for grafting rays. Finally we consider the asymptotic behaviour of iterated grafting sequences gr nλ X and show that they converge geometrically to a punctured surface.
