Almost isometries between Teichmüller spaces (1703.02687v1)
Published 8 Mar 2017 in math.GT, math.CV, and math.MG
Abstract: We prove that the Teichm\"uller space of surfaces with given boundary lengths equipped with the arc metric (resp. the Teichm\"uller metric) is almost isometric to the Teichm\"uller space of punctured surfaces equipped with the Thurston metric (resp. the Teichm\"uller metric).
