Abstract

Campaign 46 seeks a theorem which, from a seed PESC exponent

κ>0,\kappa>0,

creates a strict improvement

κκ+η.\kappa\mapsto\kappa+\eta.

Paper 56 showed that the shrinking-threshold route becomes a true amplifier after seeding, but that its good-set threshold must cross the boundary scale

ν>κ2.\nu>\frac{\kappa}{2}.

The present paper audits a different route: use a Turan power-sum zero detector to force a large prime-side observable when a boundary zero exists, then contradict that lower bound by a seed-derived upper bound.

The classical inverse short-interval method of Bombieri and Zaccagnini provides precisely such a cancellation-robust detector. For

w=1+it,w=1+it,

define

Dw(x)=xxA0x<nyΛ(n)1nw2dyy.\mathcal D_w(x) = \int_x^{x^{A_0}} \left| \sum_{x<n\le y} \frac{\Lambda(n)-1}{n^w} \right|^2 \frac{dy}{y}.

A classical Turan detector theorem states that, if the zeta function has a zero in the circle

swr,|s-w|\le r,

then for suitable absolute constants and every sufficiently large xx,

Dw(x)C(logx)3xCr.\boxed{ \mathcal D_w(x) \gg_C (\log x)^3x^{-Cr}. }

On the other hand, seed PESC (κ)(\kappa) implies the pointwise estimate

A(u):=ψ(u)uu1κ/2+o(1).A(u):=\psi(u)-u \ll u^{1-\kappa/2+o(1)}.

Partial summation then gives, for tT|t|\le T and xTBx\ge T^B,

Dw(x)xκ+2/B+o(1).\boxed{ \mathcal D_w(x) \ll x^{-\kappa+2/B+o(1)}. }

Comparing the two bounds shows that the classical detector can contradict a zero only when

Cr<κ2B.\boxed{ Cr < \kappa-\frac{2}{B}. }

Letting BB grow, the best radius reachable by this architecture is approximately

r<κC.r<\frac{\kappa}{C}.

But the seed itself already excludes zeros with

1β<κ2.1-\beta<\frac{\kappa}{2}.

Therefore a Turan-Gallagher detector with

C2C\ge2

cannot strictly amplify the seed. The classical quantitative constants are much larger than 22, so the published detector is decisively on the non-amplifying side.

The paper then analyzes a seed-shifted detector which uses the Mellin transform directly at the seeded boundary

σ0=1κ2.\sigma_0 = 1-\frac{\kappa}{2}.

Define

M(s)=1A(x)xs1dx.\mathcal M(s) = \int_1^\infty A(x)x^{-s-1}\,dx.

PESC (κ)(\kappa) gives analyticity for

s>σ0.\Re s>\sigma_0.

For fixed r>0r>0 and every integer m0m\ge0, dyadic Cauchy-Schwarz gives the derivative growth

M(m)(σ0+r+it)rm!(Cr)m+1.\boxed{ \left| \mathcal M^{(m)} (\sigma_0+r+it) \right| \ll_r m! \left( \frac{C}{r} \right)^{m+1}. }

This has exactly the same critical order as a pole on the seed boundary. Indeed, the model

Eρ(x)=xρ,ρ=σ0+iγ,E_{\rho}(x)=x^{\rho}, \qquad \rho=\sigma_0+i\gamma,

satisfies the seed dyadic mean-square exponent

X2XEρ(x)2dxX3κ,\int_X^{2X}|E_\rho(x)|^2dx \asymp X^{3-\kappa},

while its Mellin transform is exactly

1sρ,\frac{1}{s-\rho},

whose derivatives at s=ρ+rs=\rho+r are

m!rm+1.\boxed{ \frac{m!}{r^{m+1}}. }

For the actual Chebyshev error, a boundary zero produces the same pole order in the Mellin transform through

ζ(s)ζ(s)=sM(s)+ss1.-\frac{\zeta'(s)}{\zeta(s)} = s\mathcal M(s) + \frac{s}{s-1}.

Thus the seed-shifted derivative detector is critically saturated: the seed upper bound and a boundary-pole lower bound have identical r(m+1)r^{-(m+1)} growth.

This yields a no-free-coercivity theorem. Neither the classical Re (s)=1(s)=1 Turan detector nor a seed-shifted Mellin derivative detector can create a strict strip gap using PESC (κ)(\kappa) alone. A successful detector theorem must contain a genuinely new prime-side excess saving beyond the critical seed scale.

The paper defines one such explicit frontier. If a prime-side Turan-Gallagher detector upper bound

Dw(x)xλ+o(1)\mathcal D_w(x) \ll x^{-\lambda+o(1)}

were proved with

λ>Cκ2,\boxed{ \lambda>\frac{C\kappa}{2}, }

then the classical detector would exclude the seeded boundary and create a strict fixed strip improvement. The seed gives only λ=κ\lambda=\kappa, so for C>2C>2 this target requires a substantial new arithmetic gain and is inefficient compared with the shrinking-threshold frontier F-RH-017.

SG3 therefore closes the standard single-zero detector route as a method barrier and passes the campaign to SG4: search for a genuinely nonlinear or arithmetic contraction mechanism which distinguishes the von Mangoldt sequence from the critically saturated Mellin power mode.

No RH theorem is claimed.


1. Entry state

Assume PESC (κ)(\kappa) for fixed

0<κ<1.0<\kappa<1.

Papers 55–56 give

β1κ2\boxed{ \beta_* \le 1-\frac{\kappa}{2} }

and

A(x)=ψ(x)xx1κ/2+o(1).\boxed{ A(x) = \psi(x)-x \ll x^{1-\kappa/2+o(1)}. }

Set

σ0=1κ2.\boxed{ \sigma_0 = 1-\frac{\kappa}{2}. }

Campaign 46 / SG3 asks whether a single zero at or just to the left of this boundary can be detected by a prime-side observable with enough coercivity to force

β<σ0.\beta_* < \sigma_0.

2. Classical Turan-Gallagher prime detector

For

w=1+it,2tT,w=1+it, \qquad 2\le|t|\le T,

define

Pw(x,y)=x<nyΛ(n)1nw.\boxed{ P_w(x,y) = \sum_{x<n\le y} \frac{\Lambda(n)-1}{n^w}. }

Define the multiplicative detector energy

Dw(x)=xxA0Pw(x,y)2dyy.\boxed{ \mathcal D_w(x) = \int_x^{x^{A_0}} |P_w(x,y)|^2 \frac{dy}{y}. }

A classical result in the Bombieri-Turan-Zaccagnini inverse theory gives the following.

External detector input

There exist absolute constants

A01,B01,C0>2A_0\ge1, \qquad B_0\ge1, \qquad C_0>2

such that, for an admissible detector radius rr, if the Riemann zeta function has a zero in

swr,|s-w|\le r,

then for every

BB0,xTB,B\ge B_0, \qquad x\ge T^B,

and every

C>C0,C>C_0,

one has

Dw(x)C(logx)3xCr.\boxed{ \mathcal D_w(x) \gg_C (\log x)^3x^{-Cr}. }

The published quantitative proof is based on Turan's Second Main Theorem and a Gallagher conversion to short-interval prime coefficient energy.

The constants are not claimed to be optimal.

The only feature needed below is that the zero-distance exponent is multiplied by a fixed detector loss CC.


3. Seed upper bound for the same detector

By partial summation,

Pw(x,y)=A(y)ywA(x)xw+wxyA(u)uw1du.\boxed{ P_w(x,y) = A(y)y^{-w} - A(x)x^{-w} + w \int_x^y A(u)u^{-w-1}\,du. }

Since

w=1\Re w=1

and

A(u)u1κ/2+ε,A(u) \ll u^{1-\kappa/2+\varepsilon},

for every fixed

0<ε<κ2,0<\varepsilon<\frac{\kappa}{2},

we have

A(y)yw+A(x)xwxκ/2+ε.|A(y)y^{-w}| + |A(x)x^{-w}| \ll x^{-\kappa/2+\varepsilon}.

Moreover,

wxyA(u)uw1du(1+t)xu1κ/2+εduκ,ε(1+t)xκ/2+ε.\begin{aligned} \left| w \int_x^y A(u)u^{-w-1}\,du \right| &\ll (1+|t|) \int_x^\infty u^{-1-\kappa/2+\varepsilon}\,du \\ &\ll_{\kappa,\varepsilon} (1+|t|) x^{-\kappa/2+\varepsilon}. \end{aligned}

Thus

Pw(x,y)(1+T)xκ/2+o(1).\boxed{ |P_w(x,y)| \ll (1+T) x^{-\kappa/2+o(1)}. }

If

xTB,x\ge T^B,

then

Tx1/B.T\le x^{1/B}.

Hence

Pw(x,y)2xκ+2/B+o(1).\boxed{ |P_w(x,y)|^2 \ll x^{-\kappa+2/B+o(1)}. }

Since

xxA0dyy=(A01)logx,\int_x^{x^{A_0}}\frac{dy}{y} = (A_0-1)\log x,

we obtain:

Theorem 3.1 — Seed upper bound for the classical detector

For every fixed admissible BB,

Dw(x)xκ+2/B+o(1).\boxed{ \mathcal D_w(x) \ll x^{-\kappa+2/B+o(1)}. }

Create:

CERTIFIED

4. Classical detector amplification test

Suppose a zero lies in

swr.|s-w|\le r.

The external lower bound and Theorem 3.1 would give simultaneously

xCrDw(x)xκ+2/B+o(1).x^{-Cr} \ll \mathcal D_w(x) \ll x^{-\kappa+2/B+o(1)}.

For large xx, these are incompatible only if

Cr<κ2B.\boxed{ Cr < \kappa-\frac{2}{B}. }

Thus the detector can exclude at most

r<κ2/BC.\boxed{ r < \frac{ \kappa-2/B }{C}. }

Letting BB be arbitrarily large yields the limiting detector radius

rTGκC.\boxed{ r_{\rm TG} \le \frac{\kappa}{C}. }

The seed zero-free half-plane already excludes a zero at the same ordinate whenever its horizontal distance from s=1\Re s=1 is

1β<κ2.\boxed{ 1-\beta < \frac{\kappa}{2}. }

Therefore:

Theorem 4.1 — Classical Turan-Gallagher no-amplification criterion

A detector of the form above can strictly improve the seed only if

C<2.\boxed{ C<2. }

If

C=2,C=2,

it can at best recover the seed boundary.

If

C>2,C>2,

it certifies only a weaker interior part of the zero-free region already known from the seed.

The classical quantitative Zaccagnini-Bombieri constants satisfy

C02.C_0\gg2.

Thus the standard published detector architecture cannot amplify PESC (κ)(\kappa).

Create:

O-RH-136
CLASSICAL_TURAN_GALLAGHER_SINGLE_ZERO_DETECTOR_LOSES_TOO_MUCH_TO_AMPLIFY_A_PESC_SEED
CERTIFIED_AS_METHOD_BARRIER

This is a barrier for the quantified classical detector, not a theorem that every possible Turan refinement must have C2C\ge2.


5. Detector excess exponent

The preceding calculation suggests a clean arithmetic target.

Suppose instead that one proves

Dw(x)xλ+o(1)\boxed{ \mathcal D_w(x) \ll x^{-\lambda+o(1)} }

for a fixed exponent λ>0\lambda>0.

The same Turan lower bound excludes zeros whenever

Cr<λ.Cr<\lambda.

To push the zero-free boundary strictly beyond the seed line

1β=κ2,1-\beta=\frac{\kappa}{2},

one needs

λ>Cκ2.\boxed{ \lambda > \frac{C\kappa}{2}. }

Define:

F-RH-018
SEEDED_TURAN_GALLAGHER_DETECTOR_EXCESS_POWER

Target:

λ>Cκ2.\boxed{ \lambda > \frac{C\kappa}{2}. }

The seed itself supplies only

λ=κ\lambda=\kappa

in the limit BB\to\infty.

Therefore for C>2C>2, F-RH-018 requires an arithmetic gain substantially stronger than the seed exponent.

This makes the classical detector less economical than F-RH-017, whose exceptional-set bridge only needs to cross the boundary threshold by an arbitrarily small fixed amount.


6. Why recentering the detector is natural

The classical detector works on the absolute-convergence line

s=1.\Re s=1.

After a seed exists, that line is unnecessarily far from the active zero boundary

σ0=1κ2.\sigma_0 = 1-\frac{\kappa}{2}.

Paper 20 and Paper 53 give the prime-error Mellin transform

M(s)=1A(x)xs1dx\boxed{ \mathcal M(s) = \int_1^\infty A(x)x^{-s-1}\,dx }

with

ζ(s)ζ(s)=sM(s)+ss1.-\frac{\zeta'(s)}{\zeta(s)} = s\mathcal M(s) + \frac{s}{s-1}.

PESC (κ)(\kappa) gives holomorphy of M\mathcal M in

s>σ0.\boxed{ \Re s>\sigma_0. }

This suggests a seed-shifted detector at

s=σ0+r+it.s=\sigma_0+r+it.

The next sections show that the seed-shifted route removes the large absolute-line distance, but becomes exactly critically saturated.


7. Derivative bounds from the seed dyadic mean square

PESC (κ)(\kappa) gives, for every fixed ε>0\varepsilon>0,

X2XA(x)2dxεX3κ+ε.\int_X^{2X} |A(x)|^2dx \ll_\varepsilon X^{3-\kappa+\varepsilon}.

For an integer

m0,m\ge0,

differentiate the Mellin transform:

M(m)(s)=(1)m1A(x)(logx)mxs1dx.\boxed{ \mathcal M^{(m)}(s) = (-1)^m \int_1^\infty A(x) (\log x)^m x^{-s-1}\,dx. }

Fix

r>0r>0

and take

s=σ0+r+it.s=\sigma_0+r+it.

On a dyadic block

Xx2X,X\le x\le2X,

Cauchy-Schwarz gives

X2XA(x)(logx)mxs1dxε(logX)mX(3κ+ε)/2Xσ0r1/2=(logX)mXr+ε/2.\begin{aligned} \left| \int_X^{2X} A(x) (\log x)^m x^{-s-1}\,dx \right| &\ll_\varepsilon (\log X)^m X^{(3-\kappa+\varepsilon)/2} X^{-\sigma_0-r-1/2} \\ &= (\log X)^m X^{-r+\varepsilon/2}. \end{aligned}

Choose, for example,

ε=r.\varepsilon=r.

Then the dyadic block is

r(logX)mXr/2.\ll_r (\log X)^m X^{-r/2}.

Summing over

X=2jX=2^j

uses

j0jmeajm!am1.\sum_{j\ge0} j^m e^{-aj} \ll m!a^{-m-1}.

Therefore:

Theorem 7.1 — Seed-shifted Mellin derivative growth

For each fixed r>0r>0,

M(m)(σ0+r+it)rm!(Crr)m+1\boxed{ \left| \mathcal M^{(m)} (\sigma_0+r+it) \right| \ll_r m! \left( \frac{C_r}{r} \right)^{m+1} }

uniformly in real tt and integers m0m\ge0.

At the level of the distance exponent, the seed permits precisely

r(m+1).r^{-(m+1)}.

The constants are not asserted uniform as r0r\downarrow0, because the PESC o(1)o(1) exponent does not provide such quantitative boundary uniformity.


8. Exact critical model

Consider

Eρ(x)=xρ,ρ=σ0+iγ.\boxed{ E_\rho(x) = x^\rho, \qquad \rho=\sigma_0+i\gamma. }

Then

X2XEρ(x)2dx=X2Xx2σ0dxX2σ0+1.\int_X^{2X} |E_\rho(x)|^2dx = \int_X^{2X} x^{2\sigma_0}dx \asymp X^{2\sigma_0+1}.

Since

2σ0+1=3κ,2\sigma_0+1 = 3-\kappa,

the model exactly saturates the PESC (κ)(\kappa) dyadic mean-square exponent:

X2XEρ(x)2dxX3κ.\boxed{ \int_X^{2X}|E_\rho(x)|^2dx \asymp X^{3-\kappa}. }

Its Mellin transform is explicit:

1Eρ(x)xs1dx=1sρ\boxed{ \int_1^\infty E_\rho(x)x^{-s-1}dx = \frac1{s-\rho} }

for

s>σ0.\Re s>\sigma_0.

Hence

dmdsm1sρs=ρ+r=m!rm+1.\boxed{ \left| \frac{d^m}{ds^m} \frac1{s-\rho} \right|_{s=\rho+r} = \frac{m!}{r^{m+1}}. }

Thus the derivative growth permitted by Theorem 7.1 is attained, in its exact distance exponent, by the seed-critical boundary mode.

9. Actual zeta boundary pole has the same order

If the actual zeta function had a zero

ρ=σ0+iγ\rho = \sigma_0+i\gamma

of multiplicity mρm_\rho, then

ζ(s)ζ(s)-\frac{\zeta'(s)}{\zeta(s)}

would have a pole

mρsρ.-\frac{m_\rho}{s-\rho}.

Since

ζ(s)ζ(s)=sM(s)+ss1,-\frac{\zeta'(s)}{\zeta(s)} = s\mathcal M(s) + \frac{s}{s-1},

the Mellin transform has local form

M(s)=mρρ(sρ)+holomorphic term.\boxed{ \mathcal M(s) = -\frac{ m_\rho }{ \rho(s-\rho) } + \text{holomorphic term}. }

Therefore, at

s=ρ+r,s=\rho+r,

the pole contribution to the mm -th derivative has size

ρmρm!rm+1.\boxed{ \asymp_\rho \frac{ m_\rho m! }{ r^{m+1} }. }

The seed upper bound and the boundary-pole lower growth therefore have the same critical power of rr and mm.

A Turan power-sum selection among derivatives cannot create a distance exponent margin from the seed alone.


10. Critical logarithmic-time normalization

The saturation is especially transparent in logarithmic time.

Set

x=eyx=e^y

and define the seed-normalized residual

Rκ(y)=eσ0yA(ey).\boxed{ R_\kappa(y) = e^{-\sigma_0 y} A(e^y). }

Then

YY+log2Rκ(y)2dy=eY2eYA(x)2x2σ01dx.\begin{aligned} \int_Y^{Y+\log2} |R_\kappa(y)|^2dy &= \int_{e^Y}^{2e^Y} |A(x)|^2 x^{-2\sigma_0-1}\,dx. \end{aligned}

PESC (κ)(\kappa) gives

YY+log2Rκ(y)2dyeo(Y).\boxed{ \int_Y^{Y+\log2} |R_\kappa(y)|^2dy \le e^{o(Y)}. }

A boundary zero mode

Aρ(x)xσ0+iγA_\rho(x) \sim x^{\sigma_0+i\gamma}

becomes

Rκ,ρ(y)eiγy,\boxed{ R_{\kappa,\rho}(y) \sim e^{i\gamma y}, }

a persistent harmonic with constant local energy.

Thus the seed-normalized log-time space explicitly permits the boundary oscillation.

A strict exponent improvement would require genuine exponential damping in YY, not merely a change of detector coordinates.


11. No-free single-zero coercivity theorem

The preceding two detector channels fail for complementary reasons.

Absolute-line Turan-Gallagher detector

It has robust single-zero sensitivity but loses the zero distance by a factor CC:

rCr.r \mapsto Cr.

For C>2C>2 it is weaker than the seed strip.

Seed-shifted Mellin detector

It removes the absolute-line distance loss, but the seed bound itself is exactly saturated by the boundary pole:

m!rm1.\boxed{ m!r^{-m-1}. }

Therefore:

Theorem 11.1 — No-free seeded detector amplification

PESC (κ)(\kappa) alone supplies no quantitative margin in either:

  1. the classical Turan-Gallagher detector energy; or
  2. the seed-shifted Mellin derivative growth

that can force a strict zero-strip improvement.

A successful SG3 theorem must add a genuinely new arithmetic upper bound beyond the critical seed scale.

Create:

O-RH-138
NO_FREE_SINGLE_ZERO_COERCIVITY_FROM_SEED_PESC_ALONE
CERTIFIED

This is compatible with Paper 55's general no-free-amplification theorem but now applies directly to cancellation-robust zero detector architectures.


12. Relation to classical inverse short-interval theory

Zaccagnini's inverse theorem proves that sufficiently strong uniform Selberg-integral estimates force zero-density and zero-free information.

The proof explicitly uses:

  1. a Turan power-sum lower bound from a zero;
  2. a lower bound for a prime Dirichlet-polynomial detector;
  3. Gallagher's lemma;
  4. a Selberg-integral upper bound.

This is exactly the SG3 philosophy.

The present audit shows why that classical detector is not automatically an amplifier after seeding: its zero-distance exponent has a fixed constant loss.

Richards' quasi-RH short-interval theorem provides a complementary calibration. A fixed strip

ρ12+δ\Re\rho \le \frac12+\delta

implies normal prime distribution in almost all intervals of exponent exceeding 2δ2\delta, and the corresponding theorem for general signed measures is sharp at that scale.

For the CSM_RH seed,

δ=1κ2,\delta = \frac{1-\kappa}{2},

so the analytically forced short-interval scale is

α>1κ.\alpha>1-\kappa.

This supplies mesoscopic regularity but not the supercritical power accuracy

ν>κ2\nu>\frac{\kappa}{2}

required by Paper 56.

Thus known inverse and quasi-RH theory is consistent with the critical saturation found here.

A sufficient form is:

Dw(x)xλ+o(1)\boxed{ \mathcal D_w(x) \ll x^{-\lambda+o(1)} }

uniformly in the detector range, with

λ>Cκ2.\boxed{ \lambda > \frac{C\kappa}{2}. }

Then the classical Turan lower bound excludes the seeded boundary and creates a strict zero-free strip improvement.

This target is mathematically valid but probably inefficient because the classical detector constant CC is large.

Therefore F-RH-018 is recorded as a secondary, not preferred, frontier.

Alessandro Zaccagnini, Primes in almost all short intervals and the distribution of the zeros of the Riemann zeta-function, Acta Arithmetica 84 (1998), 225–244.

The inverse section uses Turan's Second Main Theorem to turn a zero into a lower bound for a Dirichlet-prime detector, then Gallagher's lemma and a Selberg-integral upper bound to control zeros.

16.2. Richards' quasi-RH short-interval calibration

Ian Richards, On the normal density of primes in short intervals, Journal of Number Theory 12 (1980), 378–384.

Under a quasi-RH strip of width δ\delta about the critical line, almost-all short-interval normality follows for interval exponent exceeding 2δ2\delta. Richards also gives a signed-measure counterexample showing sharpness of the general theorem at the boundary scale.

16.3. Pintz oscillation calibration

Classical Turan-Pintz-Revesz work shows that an individual zeta zero forces oscillation of the global prime-number-theorem error at its natural xβx^\beta scale. This confirms the role of single-zero sensitive detectors, while short intervals require additional control because a single zero contribution is reduced by the differencing factor.

18. Conclusion

The single-zero detection problem is no longer ambiguous.

Classical Turan-Gallagher machinery is cancellation-robust, but its quantitative distance loss is too large to amplify an existing PESC seed.

Moving the detector to the seeded Mellin boundary removes that geometric loss, but exposes a sharper obstruction:

the seed bound itself is pole-scale sharp.\boxed{ \text{the seed bound itself is pole-scale sharp}. }

A boundary mode has exactly the Mellin derivative growth allowed by the seed.

Therefore no linear detector can manufacture the missing exponent from existing information alone.

The next advance must distinguish the arithmetic prime sequence from the smooth critical boundary mode.

That is SG4.
