关于CM-阿贝尔簇周期的Colmez乘积公式

On Colmez's product formula for periods of CM-abelian varieties

Andrew Obus

摘要:

科尔梅兹证明了一个产品公式期间的阿贝尔簇与复乘领域K,类似于标准的产品公式在代数数论。他证明了这一猜想的合理权力2 K/Q阿贝尔。在本文中,我们完成了证明Colmez为K/Q阿贝尔消除这个权力的2。我们的证明依赖于分析Galois作用在混合特征(0,2)的Fermat曲线的De Rham上同调上,而这又依赖于理解在三点分支的射影线的Z/2^n-覆盖的稳定约化。

英文摘要:

Colmez conjectured a product formula for periods of abelian varieties with complex multiplication by a field K, analogous to the standard product formula in algebraic number theory. He proved this conjecture up to a rational power of 2 for K/Q abelian. In this paper, we complete the proof of Colmez for K/Q abelian by eliminating this power of 2. Our proof relies on analyzing the Galois action on the De Rham cohomology of Fermat curves in mixed characteristic (0, 2), which in turn relies on understanding the stable reduction of Z/2^n-covers of the projective line, branched at three points.
