论文摘要
我们证明，对于任何合理连接的三倍$ x $，都存在一个光滑的投射表面$ s $和$ 1 $ cycles的$ x $的家族，该$ x $由$ s $参数化，诱导了亚伯 - 雅各比异态$ {\ rm alb alb}（\ rm alb}（s）（s）\ cong j^3（x）$。该声明以前以一些平滑的Fano三倍而闻名。
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 ${\rm Alb}(S)\cong J^3(X)$. This statement was previously known for some classes of smooth Fano threefolds.
