 and global mirror symmetry - Iritani\, H (Kyoto)

DESCRIPTION:Under Landau-Ginzburg/Calabi-Yau correspondence\, the quantum 
 cohomology of a weighted projective hypersurface is analytically continued
  to the FJRW quantum ring of the associated Landau-Ginzburg model. Via the
  Gamma integral structure\, we will see that the analytic continuation is 
 induced from Orlov's equivalence between the derived category of coherent 
 sheaves and the category of matrix factorizations. We also mention to a re
 lation to mirror symmetry. This is based on joint work with Alessandro Chi
 odo and Yongbin Ruan. \n
