    • Abstract:Gromov-Witten (GW) theory counts complex curves in a Calabi-Yau
      (CY) manifold. In many cases the manifold admits Landau-Ginzburg (LG) phases,
      and the LG counting also enjoys symplectic and algebro-geometric constructions.
      Recently a new moduli space, called mixed spin p field, is provided to quantize
      the parameter linking CY to LG phases. One of its consequence is recovery of
      Zinger's formula on g=1 quintic GW invariants.
