On the r-rank Artin Conjecture, II

چکیده
For any nitely generated subgroup of Q we compute a formula for the density of the primes for which the reduction modulo p of contains a primitive root modulo p. We use this to conjecture a characterization of \optimal" subgroups (i.e. subgroups that have maximal density). We also improve the error term in the asymptotic formula of [9, Theorem 1.1]. 3

On Silverman's conjecture for a family of elliptic curves
Let $E$ be an elliptic curve over $Bbb{Q}$ with the given Weierstrass equation $ y^2=x^3+ax+b$. If $D$ is a squarefree integer, then let $E^{(D)}$ denote the $D$-quadratic twist of $E$ that is given by $E^{(D)}: y^2=x^3+aD^2x+bD^3$. Let $E^{(D)}(Bbb{Q})$ be the group of $Bbb{Q}$-rational points of $E^{(D)}$. It is conjectured by J. Silverman that there are infinitely many primes $p$ for which $...
متن کاملBeilinson-flach Elements and Euler Systems Ii: the Birch-swinnerton-dyer Conjecture for Hasse-weil-artin L-series
Let E be an elliptic curve over Q and let be an odd, irreducible twodimensional Artin representation. This article proves the Birch and Swinnerton-Dyer conjecture in analytic rank zero for the Hasse-WeilArtin L-series L(E, , s), namely, the implication L(E, , 1) = 0 ⇒ (E(H)⊗ ) = 0, where H is the finite extension of Q cut out by . The proof relies on padic families of global Galois cohomology c...
متن کاملDiagonal Cycles and Euler Systems Ii: the Birch and Swinnerton-dyer Conjecture for Hasse-weil-artin L-functions
This article establishes new cases of the Birch and Swinnerton-Dyer conjecture in analytic rank 0, for elliptic curves over Q viewed over the fields cut out by certain self-dual Artin representations of dimension at most 4. When the associated L-function vanishes (to even order ≥ 2) at its central point, two canonical classes in the corresponding Selmer group are constructed and shown to be lin...
متن کاملOn the r-rank Artin Conjecture
We assume the generalized Riemann hypothesis and prove an asymptotic formula for the number of primes for which Fp can be generated by r given multiplicatively independent numbers. In the case when the r given numbers are primes, we express the density as an Euler product and apply this to a conjecture of Brown–Zassenhaus (J. Number Theory 3 (1971), 306–309). Finally, in some examples, we compa...
متن کاملK 3 surfaces with Picard rank 20 over Q
We compute all K3 surfaces with Picard rank 20 over Q. Our proof uses modularity, the Artin-Tate conjecture and class group theory. With different techniques, the result has been established by Elkies to show that Mordell-Weil rank 18 over Q is impossible for an elliptic K3 surface. We also apply our methods to general singular K3 surfaces, i.e. with geometric Picard rank 20, but not necessaril...
