Number Theory — Skewes number cascade report¶
Cascade: A ∘ J ∘ L ∘ K ∘ N ∘ M (six classes) Partition: #19 of PR #677 Status: verdict (a) SURVIVES — Class K pin-slot at zero of Li(x) − π(x) IS exact framework reading of the conjecture; first crossing location remains open in [10¹⁹, 1.397×10³¹⁶]
Class breakdown¶
| Class | Role |
|---|---|
| A | content-hash of (year, bound) |
| J | π(x) prime-counting function |
| L | Li(x) = logarithmic integral |
| K | pin-slot at zero of Li(x) − π(x); sign change location |
| N | small-denom anchors in bound exponents |
| M | HDC bind across iterated upper-bound improvements |
Historical bound progression¶
| Year | Bound | log₁₀(bound) | Anchor |
|---|---|---|---|
| 1933 | 10{10} | tower | Skewes (assuming RH) |
| 1955 | 10{10} | tower | Skewes (no RH) |
| 1966 | ~1.65×10^{1165} | 1165 | Lehman |
| 1987 | ~6.658×10^{370} | 370 | te Riele |
| 2000 | ~1.397×10^{316} | 316 | Bays-Hudson (current best) |
| 2025 | first crossing > 10^{19} | 19 | computational lower bound |
Framework reading: per [[project_a_n_operators_are_harmonic_objects_themselves]] §B, the unknown crossing location IS substrate-DoF inaccessibility at the Li-vs-π Class L cascade — the bound progression IS substrate-perfect-math closing-the-window-from-above; the lower-bound-vs-upper-bound gap [10¹⁹, 10³¹⁶] is the substrate-instance-variation residual.
Verdict¶
(a) SURVIVES — Littlewood 1914 PROVED infinite sign changes; first crossing location remains open; bound improvements ARE Class K pin-slot localisation.
Per [[feedback_no_lineage_claims_in_notebook]]: does not claim to solve.
