A characterization of short curves of a Teichmueller geodesic

Kasra Rafi

Abstract. We provide a combinatorial condition characterizing curves that are short along a Teichmueller geodesic. This condition is closely related to the condition provided by Minsky for curves in a hyperbolic 3-manifold to be short. We show that short curves in a hyperbolic manifold homeomorphic to S x R are also short in the corresponding Teichmueller geodesic, and we provide examples demonstrating that the converse is not true.

Keywords. Teichmueller space, geodesic, short curves, complex of curves, Kleinian group, bounded geometry
