- Abstract
- We prove the crepant transformation conjecture for relative Grassmann flops over a smooth base B. We show that the I-functions of the respective GIT quotients are related by analytic continuation and a symplectic transformation. We verify that the symplectic transformation is compatible with Iritani's integral structure, that is, that it is induced by a Fourier-Mukai transform in K-theory.
