三次曲面和三重曲面的算术Torelli映射

Arithmetic Torelli maps for cubic surfaces and threefolds

Jeff Achter

摘要:

人们早就知道,对于一个复杂的三次曲面或三次曲面,人们可以正则地把一个主要极化的阿贝尔簇联系起来。我们给出了一个适用于算术基上的三次函数的构造。这回答了,远离素数2,德利涅的一个老问题和库德拉和拉波波特最近的一个问题。我们进一步分类的Mumford-Tate群的阿贝尔簇出现,并给出额外的算术应用。

英文摘要:

It has long been known that to a complex cubic surface or threefold one can canonically associate a principally polarized abelian variety. We give a construction which works for cubics over an arithmetic base. This answers, away from the prime 2, an old question of Deligne and a recent question of Kudla and Rapoport. We further classify the Mumford-Tate groups of the abelian varieties which arise, and give additional arithmetic applications.
