Some Motivic Properties of Gushel-Mukai Sixfolds

Michele Bolognesi, Robert Laterveer

AI总结:

本文研究了Gushel-Mukai六维流形的动机性质,证明其在代数等价意义下允许乘性Chow-Künneth分解并具有Franchetta性质,同时附带证明了双重EPW六维簇及相关立方的Franchetta性质与Chow环的消没结果。

摘要:

Gushel-Mukai六维流形是所谓Fano-K3簇的重要一类。本文证明它们在代数等价意义下允许乘性Chow-Künneth分解,并具有Franchetta性质。作为附带结果,我们证明双重EPW六维簇及其立方体在代数等价意义下具有Franchetta性质,并给出Gushel-Mukai六维流形的Chow环的一些消没结果。

英文摘要:

Gushel-Mukai sixfolds are an important class of so-called Fano-K3 varieties. In this paper we show that they admit a multiplicative Chow-Künneth decomposition modulo algebraic equivalence and that they have the Franchetta property. As side results, we show that double EPW sextics and cubes have the Franchetta property, modulo algebraic equivalence, and some vanishing results for the Chow ring of Gushel-Mukai sixfolds.
