Abstract

AA be an abelian variety over a number field KK of dimension rr, a1,,agA(K)a_1, \dots, a_g \in A(K) and F/KF/K a finite Galois extension. We consider the density of primes p\frak p of KK such that the quotient Aˉ(k(p))/aˉ1,,aˉg\bar{A}(k({\frak p}))/\langle \bar{a}_1,\dots,\bar{a}_g\rangle has at most 2r12r-1 cyclic components and p\frak p satisfies a Frobenius condition with respect to F/KF/K, where Aˉ\bar{A} is the reduction of AA modulo p\frak p, k(p)k(\frak p) is the residue class field of p\frak p and aˉ1,,aˉg\langle \bar{a}_1,\dots,\bar{a}_g\rangle is the subgroup generated by the reductions aˉ1,,aˉg\bar{a}_1,\dots,\bar{a}_g. We develop a general framework to prove the existence of the density under the Generalized Riemann Hypothesis.
