DESCRIPTION:Speakers: Amanda Hirschi (MPIM)\n\nMPI Topology Seminar\nIn or
 der to prove that homological mirror symmetry implies enumerative mirror s
 ymmetry\, one has to extract the Gromov-Witten theory of a symplectic mani
 fold from its Fukaya category. Costello outlined a strategy in 2007\, whic
 h involves the notion of a topological conformal field theory. I will defi
 ne and describe the construction of a variant of a TCFT\, called an open-c
 losed DMFT\, which relies on moduli spaces of stable maps with boundary on
  a Lagrangian submanifold. In particular\, I will explain how to deal with
  common difficulties\, such as curve and lack of transversality. This is j
 oint work with Kai Hugtenburg and no prior knowledge of symplectic geometr
 y is assumed.\n\nhttps://math-events.uni-bonn.de/event/1775/
