DESCRIPTION:Title: The coarse Helly property\, hierarchical hyperbolicity\,
  and semihyperbolicity.\n\nAbstract: For any hierarchically hyperbolic gro
 up\, and in particular any mapping class group\, we define a new metric th
 at satisfies a coarse Helly property. This enables us to deduce that the g
 roup is semihyperbolic\, i.e. that it admits a bounded quasigeodesic bicom
 bing\, and also that it has finitely many conjugacy classes of finite subg
 roups. This has several other consequences for the group. This is a joint 
 work with Nima Hoda and Harry Petyt.\n\nLink: https://mcgill.zoom.us/j/989
