论文摘要
我们表明，在其第三个格里菲斯组中，有无限的2个扭矩具有光滑的复杂射击品种。因此，格里菲斯小组的扭转亚组通常不是有限生成的，从而解决了1992年以来的Schoen问题。
We show that there are smooth complex projective varieties with infinite 2-torsion in their third Griffiths groups. It follows that the torsion subgroup of Griffiths groups is in general not finitely generated, thereby solving a problem of Schoen from 1992.
