Weighted special cycles on Rapoport--Zink spaces with almost self-dual level
Qiao He, Zhiyu Zhang, Baiqing Zhu
We introduce a ``vector valued'' version of special cycles on GSpin Rapoport--Zink spaces with almost self-dual level in the context of the Kudla program, with certain linear invar…

Intersections of Hecke correspondences on modular curves
Qiao He, Baiqing Zhu
We compute the arithmetic intersections of Hecke correspondences on the product of integral model of modular curve and relate it to the derivatives of certain Si…
