The distribution of group structures on elliptic curves over finite prime fields
Documenta mathematica, Tome 11 (2006), pp. 119-142
We determine the probability that a randomly chosen elliptic curve E/Fp over a randomly chosen prime field Fp has an l-primary part E(Fp)[l∞] isomorphic with a fixed abelian l-group Hα,β(l)=Z/lα×Z/lβ.
