What We Know
- The first 3 primes {2, 3, 5} capture 95%+ of ζ(s) at integer s — structure is massively concentrated in the smallest primes
| s | N=3 primes | N=10 | N=50 |
|---|---|---|---|
| 2 (integer) | 95.0% | 99.3% | 99.95% |
| 3/2 (prime ratio) | 81.1% | 94.0% | 98.9% |
| 7/5 (prime ratio) | 75.1% | 90.6% | 98.0% |
- At rational s = p/q near 1, convergence is much slower — more primes contribute meaningfully. Near the critical strip, prime structure is maximally distributed.
- Prime-indexed truncation points (N = 2, 3, 5, 7…) show larger jumps in the partial product than composite-indexed points. The Euler product “breathes” at prime truncations.
- At s = 7/5 (closest to critical line), the first prime alone captures only 52.8% — remaining 47% distributed across all other primes
- Analytic continuation to complex s “smears” discrete prime-breathing into a smooth function. Restricting to rational s reveals discrete prime structure most clearly.
- The “1-2% irrationality penalty” from Q-ZZ-01 may be recoverable by working at rational zeta arguments
What We Don’t Know
- Q-EM-01: Do partial Euler products at s = p/q predict v3/v4 resonance better than full ζ values?
- Q-EM-02: Is there a “discrete rational zeta” function defined only at s ∈ ℚ with cleaner prime structure than ζ(s)?
- Q-EM-03: At s = 3/2, do partial products at N = {2,3,5} form a coprime triple?
- What happens at s = 1 + 1/p for various primes p? (Approach to the pole along prime rationals)
Relationships
- [[zeta-zeros-physical]] — extends (strong): Rational s values preserve arithmetic structure that complex continuation destroys; connects to the “lossy encoding” insight
- [[coprimality]] — supports (moderate): The 95% concentration in {2,3,5} means coprimality of the first three primes governs most of ζ(s)
- [[prime-harmonic-transform]] — depends-on (strong): PHT weight function IS the Euler product; PHT with w(n)=1/nˢ is literally a Dirichlet series evaluation
- [[square-root-problem]] — extends (moderate): Rational s values reveal structure that irrational/complex s hides
- [[six-dimensional-scaffold]] — supports (moderate): {2,3,5} = first three primes; 2×3=6 is the scaffold, and they capture 95% of ζ
Bridging Potential
- If combined with [[prime-harmonic-transform]], the Euler product structure could inform better PHT weight functions
- A “discrete rational zeta” could provide a cleaner mathematical foundation for prime resonance theory
- The 95% concentration result is pedagogically powerful — “three primes rule the zeta function”
Key Evidence
- 95.0% convergence at s=2 with just {2,3,5}
- 75.1% at s=7/5 (near critical line) — maximum distribution
- Euler product “breathes” at prime truncation points
