Vanishing results in Chow groups for the modified diagonal cycles
We prove a sufficient condition for the vanishing of the modified diagonal cycle in the Chow group (with Q-coefficients) of the triple product of a curve over C. We exhibit infinitely many nonhyperelliptic curves, including the Fricke-Macbeath curve, the Bring curve, and two 1-dimensional families parameterized by certain Hurwitz spaces, …
