| Aug 6, 2022 at 12:54 | comment | added | Jason Starr | The homomorphism denoted by $r_*$ here, the Poincare dual of the "usual" pushforward homomorphism on homology, is a morphism of weight one (rational) Hodge structures. The kernel is also a weight one (rational) Hodge structure, which thus corresponds to an isogeny class of complex tori. | |
