论文摘要
我们提供了代数积分共同体学类别的新示例,这些示例是平滑投射复杂品种,这不是平滑次级类别的积分线性组合。我们的一些示例具有尺寸6,最低。我们认为的课程是关于非常通用曲线的雅各布人的最小同谋课。我们的主要工具是复杂的恢复主义。
We give new examples of algebraic integral cohomology classes on smooth projective complex varieties that are not integral linear combinations of classes of smooth subvarieties. Some of our examples have dimension 6, the lowest possible. The classes that we consider are minimal cohomology classes on Jacobians of very general curves. Our main tool is complex cobordism.
