DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/30/">Kn
 ots in the curve graph</a>\nby Esmee te Winkel (Warwick) as part of Geomet
 ry and topology online\n\n\nAbstract\n<p>\n        By a famous theorem of 
 Thurston the space\n        \\(\\PML\\) of projective (measured) laminatio
 ns on a five-times\n        punctured sphere is a three-sphere. An element
 ary example of a\n        projective lamination is a simple closed geodesi
 c with the\n        counting measure. This defines a map from the set of c
 urves to\n        \\(\\PML\\)\, which extends to an injective map from the
  curve\n        graph to \\(\\PML\\). The topology of the image of the cur
 ve\n        graph in \\(\\PML\\) and its complement were previously studie
 d\n        by Gabai.\n      </p>\n      <p> In this talk we will introduce
  certain finite subgraphs of\n        the curve graph of the five-times pu
 nctured sphere and\n        determine whether their image in \\(\\PML\\) i
 s knotted.\n      </p>\n
