Let X be an arithmetic scheme (i.e., separated, of finite type over SpecZ) of Krull dimension 1. For the associated zeta function ζ(X, s), we write down a formula for the special value at s = n < 0 in terms of the étale motivic cohomology of X and a regulator. We prove it in the case when for each generic point η ∈ X with charκ(η) = 0, the extension κ(η)/Q is abelian. We conjecture that the formula holds for any onedimensional arithmetic scheme. This is a consequence of the Weil-étale formalism…

Weil-\'etale cohomology and zeta-values of arithmetic schemes at negative integers
Following the ideas of Flach and Morin [11], we state a conjecture in terms of Weil-étale cohomology for the vanishing order and special value of the zeta function ζ(X, s) at s = n < 0, where X is a

Let X be a regular scheme, projective and flat over Spec \mathbb Z. We give two conjectural formulas, up to sign and powers of 2, for \zeta^*(X,r), the leading term in the series expansion of

The problem of computing the higher K-theory of a number field F , and of its rings of integers OF , has a rich history. Since 1972, we have known that the groups Kn(OF ) are finitely generated [48],
