拓扑霍赫希尔德同调与Hasse-Weil zeta函数

Topological Hochschild homology and the Hasse-Weil zeta function

Lars Hesselholt

摘要:

我们考虑圆群的Tate上同调作用于概型的拓扑霍赫希尔德同调。我们表明,在一个计划顺利和适当的情况下,在一个有限域,这种上同调理论自然引起的上同调解释的Hasse-Weil zeta函数的正规化行列式设想Deninger。在这种情况下,zeta函数的周期性由所述上同调理论的周期性反映,而两者一般都不是周期性的。

英文摘要:

We consider the Tate cohomology of the circle group acting on the topological Hochschild homology of schemes. We show that in the case of a scheme smooth and proper over a finite field, this cohomology theory naturally gives rise to the cohomological interpretation of the Hasse-Weil zeta function by regularized determinants envisioned by Deninger. In this case, the periodicity of the zeta function is reflected by the periodicity of said cohomology theory, whereas neither is periodic in general.
