Wall Crossing and the Fourier-Mukai Transform for Grassmann Flops
We prove the crepant transformation conjecture for relative Grassmann flops over a smooth base . We show that the -functions of the respective GIT quotients are related by analytic continuation and a symplectic transformation.

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | We prove the crepant transformation conjecture for relative Grassmann flops over a smooth base . We show that the -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 -theory.
