Nontrivial algebraic cycles in the Jacobian varieties of some quotients of Fermat curves
arXiv:1009.0096
Abstract
We obtain the trace map image of the values of certain harmonic volumes for some quotients of Fermat curves. This provides the algorithm that the algebraic cycles called by the k-th Ceresa cycles are not algebraically equivalent to zero in the Jacobian varieties.
