Critical-line bound

Improve one constant in a fixed theorem.

Submit an exact rational κ with a Lean proof of the fixed unconditional asymptotic theorem. A submission is accepted when κ exceeds the current record.

What is scored

A lower bound for distinct zeros on Re(s) = ½

Let N count nontrivial zeros of the Riemann zeta function with multiplicity, and let N₀* count distinct zeros on the critical line. Your score is the largest κ for which the frozen statement below is proved without assuming the Riemann hypothesis.

Trusted statement · dyadic form
theorem candidate_critical_line_bound :
  ∀ ε > 0, ∃ T₀ : ℝ, ∀ T ≥ T₀,
    (candidateKappa - ε) * (Ncount T (2 * T) : ℝ)
      ≤ N0star T (2 * T)

The build also requires the cumulative form, so a submission cannot change the displayed value by proving only a differently shaped statement.

Scoring

How scoring works

The percentage shown is for display only. The comparator uses exact terms and integer cross-multiplication.

Exact rational

Submit positive decimal strings p and q. Floating-point input is never accepted.

Strict comparison

Lean proves currentRecordKappa < candidateKappa inside the same formal environment.

Same theorem

Comparator checks exact statement equality before either kernel is allowed to certify the result.

Fixed by the challenge

A submission controls only the proof and κ.

The server accepts only one Lean source file, then the isolated verifier regenerates the target from root-owned templates.

  • Definitions of N, N₀*, and the critical line
  • Quantifier order, asymptotic window, and hypotheses
  • Current exact record and strict comparison
  • Toolchain, Mathlib tree, kernels, and axiom allowlist
  • Verifier scripts and promotion workflow
Acceptance boundary

Formal record, or supporting evidence

Only a complete formal submission changes the record.

Advances the record

Complete formal submission

An authenticated Lean upload whose generated statements, permitted axioms, and exported proof pass Lean and nanoda.

Does not advance it

Paper, computation, or partial proof

Open an issue to share the idea. Numerical evidence and expert review can guide the work but cannot certify κ.

Pinned dependencies

Every dependency is pinned by commit.
