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.

A complex domain is a nonempty connected open subset of C

Definition

A complex domain is a nonempty, connected, open subset UC. Open means open in the modulus metric of The metric topology: a set is open when every one of its points has a ball around it inside the set; closed means open complement, and connected has the meaning of Separation of a topological space, connected and disconnected spaces, clopen sets, and connected subsets. By C=R[x]/(x2+1) as the Euclidean plane and as a normed real algebra: what the identification preserves, these are exactly the usual Euclidean notions for the corresponding subset of R2.
