Weil-Etale上同调与L函数在零点的特殊值

Weil-etale cohomology and special values of L-functions at zero

Minh-Hoang Tran

摘要:

在全虚数域的整数环的谱上构造了一类$\mathbb{Z}$ -可构造层的子类的Weil-平展上同调和欧拉示性数.然后我们证明了环面型Artin L-函数在零点的特殊值是由适当的$\mathbb{Z}$ -可构造层的Weil-tale欧拉示性数给出的。作为结果的应用,我们将导出环面上L函数的特殊值及其类数的一些经典公式。

英文摘要:

We construct the Weil-étale cohomology and Euler characteristics for a subclass of the class of $\mathbb{Z}$-constructible sheaves on the spectrum of the ring of integers of a totally imaginary number field. Then we show that the special value of an Artin L-function of toric type at zero is given by the Weil-étale Euler characteristic of an appropriate $\mathbb{Z}$-constructible sheaf up to signs. As applications of our result, we will derive some classical formulas of special values of L-functions of tori and their class numbers.
