围绕周期的合理性

Around rationality of cycles

Raphael Fino

摘要:

本文证明了二次曲面的函数域上的代数圈与基域上的代数圈的合理性的比较结果。这些结果已经由Alexander Vishik在特征0的情况下证明,这使他能够使用代数配边理论。我们的证明使用的模2 Steenrod操作在周理论和工作在任何特性不同于2。

英文摘要:

In this article we prove certain results comparing rationality of algebraic cycles over the function field of a quadric and over the base field. Those results have already been proved by Alexander Vishik in the case of characteristic 0, which allowed him to work with algebraic cobordism theory. Our proofs use the modulo 2 Steenrod operations in the Chow theory and work in any characteristic different from 2.
