The CFKRS recipe prediction for elliptic-curve quadratic twists

About 1 year old · traced to

Let EE be the elliptic curve of conductor NN, with NN not a square, and let OE,k(X;S;M)\mathcal{O}_{E,k}(X;S;M) be the twisted shifted moment defined in the source. For S={s1,…,sk}S=\{s_1,\dots,s_k\} and J⊆{1,…,k}J\subseteq\{1,\dots,k\}, write SJ={sj:j∈J}S_J=\{s_j:j\in J\} and SJ−={1−sj:j∈J}S_J^{-}=\{1-s_j:j\in J\}. Define

HE,M(S):=12ζ(2)∑Mn1⋯nk=□λE(n1)⋯λE(nk)a(MNn1⋯nk)n1s1⋯nksk.H_{E,M}(S):=\frac{1}{2\zeta(2)}\sum_{Mn_1\cdots n_k=\square}\frac{\lambda_E(n_1)\cdots\lambda_E(n_k)a(MNn_1\cdots n_k)}{n_1^{s_1}\cdots n_k^{s_k}}.

CFKRS conjecture. If ∣Re⁡(s)−12∣≪1/log⁡X|\operatorname{Re}(s)-\frac12|\ll1/\log X for all s∈Ss\in S, then as X→∞X\to\infty,

OE,k(X;S;M)∼∑J⊆{1,…,k}∏j∈JXE(sj)X1+∣J∣−2∑j∈Jsjg~(1+∣J∣−2∑j∈Jsj)HE,MN∣J∣(S∖SJ∪SJ−).\mathcal{O}_{E,k}(X;S;M)\sim\sum_{J\subseteq\{1,\dots,k\}}\prod_{j\in J}\mathcal{X}_E(s_j)X^{1+|J|-2\sum_{j\in J}s_j}\widetilde g\left(1+|J|-2\sum_{j\in J}s_j\right)H_{E,MN^{|J|}}(S\setminus S_J\cup S_J^{-}).

This is the modified CFKRS prediction retaining both parities of ∣J∣|J|; the source explicitly notes that the earlier parity-restricted prediction is false for k=1k=1 because it omits a term.
