Murmuration conjecture for elliptic curves ordered by naive height

For integers A,BA,B, let EA,BE_{A,B} be the elliptic curve

y2=x3+Ax+B,y^2=x^3+Ax+B,

with no prime pp satisfying both p4Ap^4\mid A and p6Bp^6\mid B. Define its naive height by

H(EA,B)=max(4A3,27B2),H(E_{A,B})=\max(4|A|^3,27|B|^2),

and write N(E)N(E) for its conductor, ϵ(E)\epsilon(E) for its root number, and ap(E)a_p(E) for its ppth coefficient. For a set SS, let EES[f(E)]=S1ESf(E)\mathbb E_{E\in S}[f(E)]=|S|^{-1}\sum_{E\in S}f(E). Let J1J_1 be the Bessel function of the first kind, let vp(m)v_p(m) be the pp-adic valuation, and let p,ν\ell_{p,\nu} and ^p,ν\hat{\ell}_{p,\nu} be the local terms defined in the source.

For real numbers 0<C1<C20<C_1<C_2, the murmurations conjecture.

This predicts the limiting correlation between the Fourier coefficients ap(E)a_p(E) and root numbers when elliptic curves are ordered by naive height. It extends the study of murmurations beyond conductor ordering and gives an explicit expression in terms of Bessel functions and local arithmetic factors; the status of the prediction is open.
