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.

Empty-base and rank-zero Thom conventions

Conventions

The based quotient convention gives Th⁡(0B)=B+, even though the sphere bundle is empty. For B=∅, the Thom space is the one-point based space. These are the conventions already proved in Trivial Thom spaces as suspension smash products and defined in Disk bundle, sphere bundle, and Thom space: the differential topology interface. A rank-zero collapse of a union of components is the identity on that union and sends the other components to the basepoint.

Dependency tree · two levels

4 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.
