概要: 

Landau-Ginzburg/Calabi-Yau correspondence or LG/CY correspondence conjectured an equivalence relation between Gromov-Witten theory of a Calabi-Yau hypersurface of weighted projective space and the corresponding FJRW-theory. In the talk, we will survey the advance on the conjecture and recent progress using wall-crossing formula of gauged linear sigma model.
