Descendant and Fourier-Mukai equivalences for simple flops
Jiun-Cheng Chen, Hsian-Hua Tseng
For a simple flop , we construct a correspondence between genus descendant Gromov-Witten theories of and . We show that the Fourier-Mukai equivalen…
Classification of threefold canonical thresholds
Jheng-Jie Chen, Jiun-Cheng Chen, Hung-Yi Wu
We show that the set of smooth threefold canonical thresholds coincides with $\mathcal{T}_{2, \mathrm{sm}}^{\mathrm{lc}}=\mathcal{HT}_…
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…
Simple Grassmannian flops
Jiun-Cheng Chen, Hsian-Hua Tseng
We introduce a class of flops between projective varieties modelled on direct sums of universal subbundles of Grassmannians. We study basic properties of these flops.
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…
The Bogomolov-Miyaoka-Yau inequality for stacky surfaces
Jiun-Cheng Chen, Hsian-Hua Tseng
We present a generalization of the Bogomolov-Miyaoka-Yau inequality to Deligne-Mumford surfaces of general type.
