How statement and proof provenance work

The first chip identifies the source of the statement or construction; the second identifies the source of its local proof or verification.

  • Literature-sourced: the exact statement appears in a cited source; only wording and notation differ.
  • AI-adapted: a semantically identical restatement of literature-sourced material, modulo indexing, notation, and boundary cases adopted by the library.
  • AI-generated: a genuinely novel statement formulated by AI, with no source for the claim itself.

These labels describe origin, not correctness: citations and verification chips remain separate evidence.

The factorial-gap series shows that a holomorphic function need not continue past its boundary

Statement refuted

Refuted claim. Every holomorphic function on a domain analytically continues past each boundary point.

The witness is

F(z)=∑n≥0zn!,

which is holomorphic on the unit disc and has the whole unit circle as a natural boundary.

Facts & Assumptions

Given: The factorial-gap series witness.

[L1]

The factorial-gap series has radius 1 and the whole unit circle as a natural boundary (The factorial-gap series has the unit circle as a natural boundary).

Counterexample

1.1L1

Fact [L1] gives a holomorphic function on the unit disc that cannot be continued through any boundary point of that disc.

2.1step 1.1∎

Therefore the universal claim is false.

Dependency tree · two levels

5 results within two dependency steps of this one, each drawn at its shortest distance from it. An arrow runs from a result to what uses it, so the chart reads left to right and ends at this result, which carries a heavier outline. Every node is a link to that result.
