The Lang-Trotter Conjecture on primitive points is the analogue for elliptic curves of Artin's conjecture on primitive roots. Indeed, if we have an elliptic curve over with a rational point of infinite order, we may count the primes of good reduction for which generates . We formulate and investigate some natural variants of the Lang-Trotter Conjecture. For example, we require that the order of the point equals the exponent of the group : this means that the subgroup generated by the point is as large as possible, and the condition is meaningful also for non-cyclic groups. This is joint work with Alexandre Benoist.
