It is well-known that Gromov-Witten theory of the quintic threefold is related with
the FJRW theory of the Fermat polynomial on the orbifold C^5/Z_5. In particular, Givental I-functions of these theories are related by analytic continuation. This phenomenon is usually called Landau-Ginzurg/Calabi-Yau correspondence. It can be understood in terms of wall-crossing in the stability space of a certain GIT quotient. In the talk I plan to explain how this works for the quintic threefold and how to generalize this to the mirror quintic, which is a subject of my ongoing
project with Melissa Liu.
