SUMMARY:Kirk Public Lecture: Stabilizing one arc at a time - Nathalie Wahl
  (University of Copenhagen)

DESCRIPTION:Homological stability has in recent years become a computation
 al strategy: to compute the homology of certain types of objects\, it can 
 pay off to first stabilize\, letting some rank associated to the object go
  to infinity\, and then compute homology of the stable object instead. Sta
 ndard examples would be letting the rank of a matrix\, or the genus of a s
 urface go to infinity. In this talk\, I will give an introduction to these
  ideas\, and explain two somewhat unusual examples of stabilizations\, for
  mapping class groups of surfaces and for symplectic groups\, one arc (or 
 strip of paper!) at a time.&nbsp\;
