Strip maps of small surfaces are convex

Geometric Topology 2015-06-29 v1

Abstract

The strip map is a natural map from the arc complex of a bordered hyperbolic surface SS to the vector space of infinitesimal deformations of SS. We prove that the image of the strip map is a convex hypersurface when SS is a surface of small complexity: the punctured torus or thrice punctured sphere.
