DESCRIPTION:Title: <a href="https://researchseminars.org/talk/rlgts/7/">La
 rge-scale geometry of big mapping class groups</a>\nby Kathryn Mann (Corne
 ll) as part of Regensburg low-dimensional geometry and topology seminar\n\
 n\nAbstract\nMapping class groups of infinite type surfaces are not finite
 ly generated (nor even are they locally compact) groups\, but in many case
 s one can still meaningfully talk about their large scale geometry. I will
  explain joint work with Kasra Rafi on the problem of which surfaces have 
 mapping class groups with nontrivial coarse geometry\, and how this relate
 s to questions of actions on arc and curve complexes.\n
