The prime
frontier.

A machine-made claim reaches into one of mathematics’ deepest mysteries.

Primes look unpredictable. A new claim promises a sharper view of their hidden order. Let’s see what it actually says.

Simple to define.
Extraordinarily hard to predict.

Every whole number greater than one is a prime, or is made by multiplying primes. They are arithmetic’s building blocks. Yet the gaps between them keep changing.

Mathematicians can estimate how many primes lie below a given number. The deeper question is: how far can that estimate be from the truth?

That question has an extraordinary connection to the zeros of a function called zeta. A “zero” is an input that makes the function equal zero. Better knowledge of where those inputs cannot be means tighter control over the irregularity of the primes.

The claim
Move the boundary. See the difference.

A boundary.
Not the finish line.

The full Riemann Hypothesis puts every nontrivial zeta zero on one line. This claim excludes zeros from a smaller region. A striking possibility, but a different statement.

Compare the claimed zero-free regions The seven-eighths claim excludes zeros to the right of 0.875. The Riemann Hypothesis would place all nontrivial zeta zeros on the line at 0.5. No zeros are plotted in this schematic. 0½1THE RH LINEReal part of s →Vertical position represents imaginary part ⅞ ZEROFREE

These inputs have two coordinates: a real part (across) and an imaginary part (up and down). The colored area shows where the selected statement would rule out zeros.

A comparison of statements, not a numerical experiment. No zeros are plotted. For ⅞ and ¹¹⁄₁₂, only the right-hand region inside the strip is highlighted.

Compare the statements

Re(s) > 7/8

The main claim would exclude zeros to the right of this line. It still leaves a gap between the claimed boundary and the Riemann Hypothesis line.

If it holds

A major advance in understanding the distribution of primes. Not the full Riemann Hypothesis. And not, by itself, a shortcut to breaking encryption.

The evidence
A claim is the beginning of the story

Show us
the working.

A paper, a formal statement, and an independent replay answer different questions. We keep them separate so you can see exactly what has—and hasn’t—been established.

01The manuscriptWhat is being claimed?Publisher supplied

A zero-free half-plane for zeta and the stated Dirichlet and Hecke L-functions. This feature focuses on the zeta statement; the broader family has additional hypotheses and scope.

Read the 7/8 manuscript
02The formalizationWhat is reported as formalized?Not independently checked

OpenAI supplies a Lean scope note covering the 7/8 bounds for zeta, Dirichlet L-functions, and finite-order Hecke L-functions over ℚ(√−3), plus a stated logarithmic Landau–Siegel exclusion. Later applications are outside that selected statement.

Having a Lean link is not the same as independently checking its axioms, dependencies, or agreement with the manuscript.

Inspect the pinned scope note
03Our examinationWhat can we independently reproduce?Not started

The first job is to match the manuscript’s statement and assumptions to the pinned formal endpoint. Then inspect dependencies and attempt an isolated replay. No result from those checks has been recorded here.

One sign.
A different answer.

Here’s what examining a proof looks like up close.

A paper claims an extraordinary structure on the six-dimensional sphere. In our scoped replay, flipping one input changes the conditional relation determinant from 1 to 7.

The arithmetic is reproducible. Which sign the geometry supplies is still unresolved. That’s the part a successful calculation cannot answer for us.

Inputs: λ₀ = 0 · λ₁ = 1 · λ₂ = −1

This tests the encoded arithmetic, not which sign is geometrically correct. Neither setting validates the paper’s headline claim.
