چکیده

The classical n-variable Kloosterman sums over the finite field Fp give rise to a lisse Ql-sheaf Kln+1 on Gm,Fp = P 1 Fp − {0,∞}, which we call the Kloosterman sheaf. Let Lp(Gm,Fp ,Sym Kln+1, s) be the L-function of the k-fold symmetric product of Kln+1. We construct an explicit virtual scheme X of finite type over Spec Z such that the p-Euler factor of the zeta function of X coincides with Lp(Gm,Fp ,Sym Kln+1, s). We also prove similar results for ⊗Kln+1 and ∧k Kln+1.

Functional Equations of L-functions for Symmetric Products of the Kloosterman Sheaf

We determine the (arithmetic) local monodromy at 0 and at ∞ of the Kloosterman sheaf using local Fourier transformations and Laumon’s stationary phase principle. We then calculate -factors for symmetric products of the Kloosterman sheaf. Using Laumon’s product formula, we get functional equations of L-functions for these symmetric products and prove a conjecture of Evans on signs of constants o...

L-Functions for Symmetric Products of Kloosterman Sums

The classical Kloosterman sums give rise to a Galois representation of the function field unramfied outside 0 and ∞. We study the local monodromy of this representation at ∞ using l-adic method based on the work of Deligne and Katz. As an application, we determine the degrees and the bad factors of the L-functions of the symmetric products of the above representation. Our results generalize som...

Trivial factors for L-functions of symmetric products of Kloosterman sheaves

In this paper, we determine the trivial factors of L-functions of both finite and infinite symmetric products of Kloosterman sheaves. Let Fq be a finite field of characteristic p with q elements, let l be a prime number distinct from p, and let ψ : Fq → Q ∗ l be a nontrivial additive character. Fix an algebraic closure F of Fq. For any integer k, let Fqk be the extension of Fq in F with degree ...

Seventh Power Moments of Kloosterman Sums

Evaluations of the n-th power moments Sn of Kloosterman sums are known only for n 6 6. We present here substantial evidence for an evaluation of S7 in terms of Hecke eigenvalues for a weight 3 newform on Γ0(525) with quartic nebentypus of conductor 105. We also prove some congruences modulo 3, 5 and 7 for the closely related quantity T7, where Tn is a sum of traces of n-th symmetric powers of t...
