DESCRIPTION:Speaker: Felix Janda\nhosted by Tamas Hausel\nAbstract: Ever si
 nce people have studied geometry\, they have counted geometric objects. Fo
 r example\, Euclid's Elements start with the postulate that there is exact
 ly one line passing through two distinct points in the plane. The kinds of
  counting problems we are able to pose and to answer has grown significant
 ly since then. Today enumerative geometry is a rich subject with connectio
 ns to many fields\, including combinatorics\, physics\, representation the
 ory\, number theory and integrable systems.In this talk\, I will show how 
 to solve several classical counting questions. I will then move to a more 
 modern problem with roots in string theory which has been the subject of i
 ntense study for the last three decades: The computation of the Gromov-Wit
 ten invariants of the quintic threefold\, an example of a Calabi-Yau manif
 old.
