SUMMARY:Geometry & Topology Seminar
CLASS:PUBLIC
DESCRIPTION:Gromov-Witten invariants play an essential role in mirror symme
 try and\nenumerative geometry. Despite this\, there are few effective tool
 s for\ncomputing Gromov-Witten invariants of blow-ups. Blow-ups of X can b
 e\nrewritten as subvarieties of Grassmann bundles over X. In joint work\nw
 ith Tom Coates and Wendelin Lutz\, we exploit this fact and extend the\nab
 elian/non-abelian correspondence\, a modern tool in Gromov-Witten\ntheory.
  Combining these two steps allows us to get at the genus 0\ninvariants of 
 a large class of blow-ups.
