DESCRIPTION:Title: Cubical geometry in the polygonalization complex.\n\nAbs
 tract:\n\nThe polygonalization complex of a punctured surface is a cube co
 mplex whose vertices correspond to polygonal decompositions of the surface
 . Although the complex is not CAT(0)\, it is contractible and shares many 
 features of a CAT(0) cube complex. In particular\, it has a very rich fami
 ly of separating and embedded hyperplanes. We will parametrize it and char
 acterize its crossing graph via the arc complex. This is a joint work with
  M. Bell and R. Tang.\n\n \n
