Twisted L-functions over number fields and Hilbert's eleventh problem
نویسندگان
چکیده
Let K be a totally real number field, π an irreducible cuspidal representation of GL2(K)\GL2(AK) with unitary central character, and χ a Hecke character of conductor q. Then L(1/2, π ⊗ χ) ≪ (Nq) 1 2 − 1 8 , where 0 6 θ 6 1/2 is any exponent towards the Ramanujan– Petersson conjecture (θ = 1/9 is admissible). The proof is based on a spectral decomposition of shifted convolution sums and a generalized Kuznetsov formula.

HILBERT’S TENTH PROBLEM FOR FUNCTION FIELDS OF VARIETIES OVER NUMBER FIELDS AND p-ADIC FIELDS
Let k be a subfield of a p-adic field of odd residue characteristic, and let L be the function field of a variety of dimension n ≥ 1 over k. Then Hilbert’s Tenth Problem for L is undecidable. In particular, Hilbert’s Tenth Problem for function fields of varieties over number fields of dimension ≥ 1 is undecidable.
متن کاملExtensions of Hilbert's Tenth Problem
Lectures Two types of lectures were programmed into the schedule. First there were a number of introductory lectures which were were meant to introduce non-specialist into the area of Hilbert’s Tenth Problem. Since quite a few of the participants came from different backgrounds this was an ideal way to get a feeling of the problems which come up in this area of mathematics. The second type of l...
متن کاملUsing Elliptic Curves of Rank One towards the Undecidability of Hilbert's Tenth Problem over Rings of Algebraic Integers
Let F ⊆ K be number fields, and let OF and OK be their rings of integers. If there exists an elliptic curve E over F such that rkE(F ) = rkE(K) = 1, then there exists a diophantine definition of OF over OK .
متن کاملVanishing of L-functions of Elliptic Curves over Number Fields
Let E be an elliptic curve over Q, with L-function LE(s). For any primitive Dirichlet character χ, let LE(s, χ) be the L-function of E twisted by χ. In this paper, we use random matrix theory to study vanishing of the twisted L-functions LE(s, χ) at the central value s = 1. In particular, random matrix theory predicts that there are infinitely many characters of order 3 and 5 such that LE(1, χ)...
متن کاملul 2 00 2 HILBERT ’ S TENTH PROBLEM FOR ALGEBRAIC FUNCTION FIELDS OF CHARACTERISTIC 2
Let K be an algebraic function field of characteristic 2 with constant field C K. Let C be the algebraic closure of a finite field in K. Assume that C has an extension of degree 2. Assume that there are elements u, x of K with u transcendental over C K and x algebraic over C(u) and such that K = C K (u, x). Then Hilbert's Tenth Problem over K is undecidable. Together with Shlapentokh's result f...
