Vanishing results for the modified diagonal cycles II: Shimura curves

Congling Qiu, Wei Zhang

We prove vanishing results for the modified diagonal cycles in the Chow groups of the triple products of Shimura curves and their motivic direct summands. In particular we find exa…

Finiteness properties for Shimura curves and modified diagonal cycles

Congling Qiu

We prove that only finitely many Shimura curves can have gonality bounded by a given number, and we study the computability of this finite set. Motivated by the relation between hy…
