Crepant Transformation Correspondence For Toric Stack Bundles
Qian Chao, Jiun-Cheng Chen, Hsian-Hua Tseng
We prove a crepant transformation correspondence in genus zero Gromov-Witten theory for toric stack bundles related by crepant wall-crossings of the toric fibers. Specifically, we…

On the derived category of a toric stack bundle
Qian Chao, Jiun-Cheng Chen, Hsian-Hua Tseng
We establish some properties of the derived category of torus-equivariant coherent sheaves on a split toric stack bundle. Our main result is a semi-orthogonal decomposition of such…
