Descripción
For a curve C, viewed as a cycle in its Jacobian, we study its image
n_*C under multiplication by n on JC. We prove that the subgroup
generated by these cycles, in the Chow group modulo algebraic
equivalence, has rank at most d-1, where d is the gonality of C. We also
discuss some general facts on the action of n_* on the Chow groups.
