Gamma conjecture II via global Gamma-I
Jianxun Hu, Hua-Zhong Ke, Changzheng Li +1
For a Fano manifold , Gamma conjecture II aims to use to describe the asymptotic behavior of its Dubrovin connection via -integral struc…

On the quantum cohomology of blow-ups of four-dimensional quadrics
Jianxun Hu, Huazhong Ke, Changzheng Li +1
We propose a conjecture relevant to Galkin's lower bound conjecture, and verify it for the blow-ups of a four-dimensional quadric at a point or along a projective plane. We also sh…

Mirror symmetry for certain blowups of Grassmannians
Jianxun Hu, Huazhong Ke, Changzheng Li +1
We classify when the blowup of a complex Grassmannian along a smooth Schubert subvariety is Fano. We compute almost all the two-point, genus zero Gromov-Witten invari…
