Geometric representability of 1-cycles on rationally connected threefolds
Résumé
We prove that for any rationally connected threefold X, there exists a smooth projective surface S and a family of 1-cycles on X parameterized by S, inducing an Abel-Jacobi isomorphism Alb(S) ∼ = J 3 (X). This statement was previously known for some classes of smooth Fano threefolds.
