Dependency roadmap

STATUS: RIEMANN HYPOTHESIS OPEN

B PROGRAM: CONTINUE. L7 complete. L8 not started.

As of 2026-10-09, B investigates the ZFC independence of \(\rho\), the arithmetic RH sentence fixed in L2-D 1.0.0. L7 normalization and proof transfer with costs are retained limited results; no new independence connection has been obtained.

Current B and its open obligations

Object Established scope Remaining gap
Fixed \(\rho\) Explicit arithmetic construction; arithmetic equivalence in PA and RH equivalence in ZFC at the usual-mathematics level A proof, negation or unprovability result for \(\rho\) itself
L7 normalization Elimination of prime-support gaps, with integer and precision bounds PA-internal certification of global violation preservation; machine proof
Transfer in the same proof system An additional-character upper bound from a restricted section to the original section Lower bounds for all proofs; a new reduction or model input relevant to independence
I / II \(\operatorname{Con}(\mathrm{ZFC}+\neg\rho)\) / \(\operatorname{Con}(\mathrm{ZFC}+\rho)\) Both OPEN, 2 → 2

B continues by the researcher's choice. General incompleteness, restriction of an input family and proof-length upper bounds do not close these obligations. No concrete L8 plan has been adopted; L8 and Cycle 18 are not started. See the update through L7.

Finite-Weil route: HOLD

The roadmap below preserves the conditional route adopted through Cycle 17, 2026-10-08. CAP/PAR are two conditions separate from B's I/II; both remain OPEN, 2 → 2. The conditional transfer and CORE-S are retained. No universal impossibility of this route has been established.

Dependencies through Cycle 17

Node Requirement Status
CAP \(\|(I-G_{+,j})P_{N_j}R_{a_j}k\|_2\to0\) Actual capture in the full even ground space remains unproved
PAR Eventually \(e_->e_+\) on that same sequence Strict parity remains unproved
CORE-S → ES At each finite point, strict parity gives a simple even ground Auxiliary finite result; no independent \(\Delta_+>0\) obligation
Adopted transfer Real-zero structure from ES and strong-L² capture give complex locally uniform convergence Conditional implication; actual antecedents unproved
Value normalization and zero preservation After nonzero-limit and convention checks, use proxy convergence and Hurwitz/Rouché Existing implications; RH remains unproved

The resolving sequence satisfies \(a_j\to\infty\) and \(a_j/(N_j+1)\to0\). CAP and PAR must hold on the same sequence.

\[a_j\to\infty,\qquad\frac{a_j}{N_j+1}\to0,\]
\[\mathrm{CAP}:\quad\|(I-G_{+,j})P_{N_j}R_{a_j}k\|_2\to0,\]
\[\mathrm{PAR}:\quad e_-(a_j,N_j)>e_+(a_j,N_j)\quad\text{eventually}.\]
\[\mathrm{CAP}+\mathrm{PAR}\Longrightarrow\mathrm{CORE\text{-}S}/\mathrm{ES}\Longrightarrow\text{adopted transfer}\Longrightarrow\mathrm{RH}.\]

CORE-S and the joint transfer remain adopted. The ES-independent earlier CMP-R is a separate sufficient condition; its rate is not added to the joint branch. CASE D — CMP OPEN + ES OPEN.

Branches kept off the main route

Stopping point of the earlier route

No third route, truncation or generic operator theory is started automatically. The remaining question in this route is actual CAP and PAR on one sequence. Rebuilding existing transfer theory does not establish its antecedents. Cycle 17 ended without starting Cycle 18.

CMP: NOT ESTABLISHED. ES: NOT ESTABLISHED.

EVEN FULL-GROUND CAPTURE: NOT ESTABLISHED.

COFINAL COMPATIBILITY: NOT ESTABLISHED.

COFINAL INCOMPATIBILITY: NOT ESTABLISHED.

Retained derivative-route roadmap — 2026-09-30

The table and discussion below preserve the earlier roadmap before the import/CMP/ES update. Its then-pending order is historical. The program is a set of conditional dependencies, not a sequence whose later conclusions have already been proved.

Step Exact role Current status
Actual finite arithmetic system Finite Fourier restrictions of the Weil form retain the arithmetic input used in the cited construction Defined; scope recorded in local-to-global and common-parent tracks
Restricted hierarchical selection Minimizing directions in each fixed finite derivative trial space approach \(k\), under the stated support/projection hypotheses Auxiliary PROVED result in the record
Even-\(L^2\) cyclicity The union of derivative trial spaces is dense in even \(L^2\) Auxiliary PROVED, without RH
Fixed even-head spanning Each fixed head is exactly spanned by some finite derivative prefix; minimal prefix is certified in stated ranges Auxiliary PROVED; not a uniform moving-ground theorem
Uniform finite-head approximation Quantify the needed order, physical lift cost and form error along changing cutoffs OPEN
Growing-order hierarchy Control every fixed-order constant as the derivative order grows OPEN
Quantitative full-even-ground capture Approximate the varying full even ground state with controlled dimension, coefficients, and error OPEN
Parity and ES Identify a simple even lowest state on a suitable sequence of full finite systems OPEN in the required global passage
\(G^*\) comparison Compare value-normalized Fourier transforms of the actual ground and prolate proxy uniformly on the required complex sets OPEN
Proxy to \(\Xi\) Use the known proxy approximation with its exact parameter and normalization restrictions KNOWN literature input, not a statement about the actual ground
Real-zero preservation The actual finite ground has the required real-zero property when the applicable theorem's hypotheses, including ES, hold CONDITIONAL application of a KNOWN theorem
Global passage Nonzero locally uniform limit of real-zero entire approximants has no off-real zeros KNOWN Hurwitz/Rouché implication
RH Identify that limit with the actual \(\Xi\) while fulfilling every preceding obligation OPEN

Why density is not the missing comparison

For a fixed even function \(f\) and a fixed error tolerance, cyclicity supplies a finite derivative combination close to \(f\) in \(L^2\). The ground state here changes with the cutoffs. An estimate uniform in those cutoffs is a stronger statement. Small singular values, increasing derivative order, and the gap between a trial-space minimum and the full-system minimum all remain relevant.

Priority 2 adds fixed-head rank results and explicit finite conditioning certificates. The pending order is now uniform conditioning and lift estimates for changing heads, growing-dimension constants, full even-ground capture, then parity. No full-ground conclusion follows from the finite-head update.

Conditions for reopening a route

A new input must discharge an existing obligation rather than restate it. Examples include a quantitative conditioning bound for the actual derivative columns, an error estimate uniform in an admissible joint limit, or a verified comparison to the full ground state. A new name for positivity, bounded scaling, or zero-free convergence is not such an input.

See local-to-global, common parent, rate/history, and hierarchical selection for the provenance of these obligations.
