Tethered curve complexes and homology stability

Geometry of mapping class groups and Out(Fn) October 25, 2016 - October 28, 2016

October 25, 2016 (09:30 AM PDT - 10:30 AM PDT)
Speaker(s): Karen Vogtmann (University of Warwick)
Location: MSRI: Simons Auditorium
  • homological stability

  • Mapping Class Group

  • Curve Complex

We study the topology of several variations of curve complexes, then use them to give a newly streamlined proof of homology stability for surface mapping class groups.  This is joint work with Allen Hatcher.
