Convergence of zeros from finite-prime Weil minimizers to the zeta zeros

Show that, as the upper cutoff x increases (equivalently, as the finite set of primes used in the Weil quadratic form expands), the zeros of the Mellin transform of the minimizer η_x of the restricted Weil quadratic form converge to the nontrivial zeros of the Riemann zeta function.

Background

In the letter, the author describes an optimization procedure that constructs, for a finite set of primes up to x, a quadratic form whose minimizer η_x yields a Mellin transform with all zeros on the critical line. Numerically, using primes up to 13, this produces striking approximations to the first 50 zeros.

The unresolved issue is whether, as x → ∞, the zeros of these approximating functions actually converge to the true nontrivial zeros of ζ(s). Establishing such convergence would provide a path to proving the Riemann Hypothesis via Hurwitz’s theorem.

References

What we do not know is that, when we increase the upper limit, which was x=13 here, the corresponding set of zeros will converge towards the zeros of zeta. This is something which at this point is not proved.
