Abstract

Let \(E/\mathbb {Q}\) be an elliptic curve with complex multiplication (CM), and for each prime p of good reduction, let \(a_{E}(p) = p + 1 - \#E(\mathbb {F}_{p})\) denote the trace of Frobenius. By the Hasse bound, \(a_{E}(p) = 2\sqrt {p} \cos \theta _{p}\) for a unique θp∈ [0,π]. In this paper, we prove that the least prime p such that θp∈ [α,β]⊂ [0,π] satisfies
$$ p \ll \left(\frac{N_{E}}{\beta - \alpha}\right)^{A}, $$
where NE is the conductor of E and the implied constant and exponent A>2 are absolute and effectively computable. Our result is an analogue for CM elliptic curves of Linnik’s Theorem for arithmetic progressions, which states that the least prime pa (mod q) for (a,q)=1 satisfies pqL for an absolute constant L>0.
