DESCRIPTION:Sageev's cube complex dual to a collection of curves and length
 s of curves on hyperbolic surfaces.\n\nSageev gave a very general construc
 tion of a CAT(0) cube complex dual to a `space with walls'\, and this cons
 truction has proved extraordinarily useful in recent celebrated work of Ag
 ol\, Wise\, and others. In one of the simplest nontrivial settings\, this 
 construction produces a non-positively curved cube complex dual to a finit
 e collection of non-homotopic essential closed curves on a surface. I will
  show how this cube complex can be used to analyze the length function ass
 ociated to a system of curves on the moduli space of hyperbolic structures
  on a surface of genus g\, adding context to previous work of Basmajian.\n
