SUMMARY:Symplectic invariants of Calabi-Yau threefolds - Aleksander Doan (
 UCL)

DESCRIPTION:This talk is about various curve counting invariants of Calabi
 -Yau threefolds or\, more generally\, symplectic manifolds of real dimensi
 on six.  After a brief overview of the subject\, I will discuss joint work
  with E. Ionel and T. Walpuski on the Gopakumar-Vafa finiteness conjecture
  and an ongoing project with T. Walpuski\, whose goal is to combine ideas 
 from gauge theory\, holomorphic curve theory\, and geometric analysis to d
 efine new invariants of symplectic six-manifolds.
