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.

Whitney sums of vector bundles

Definition

Let $E \to M$ and $F \to M$ be smooth vector bundles over the same base. Their Whitney sum is the disjoint union

$E \oplus F : = ∐_{p \in M} (E_{p} \oplus F_{p}),$

with projection sending $(p, v, w)$ to $p$ . Fibrewise, the vector space over $p$ is the direct sum of $E_{p}$ and $F_{p}$ .

Dependency tree · two levels

11 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.
