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.

C2-cofiniteness

Definition

For a complex vertex algebra $V$ , define

C_{2} (V) : = {span}_{C} {u_{(- 2)} v : u, v \in V},

where $u_{(- 2)} v$ is the $(- 2)$ -mode product in the state-field convention of Vertex algebra in the state–field convention. The vertex algebra is $C_{2}$ -cofinite if the quotient vector space $V / C_{2} (V)$ is finite dimensional. This definition alone does not assert rationality, semisimplicity, finite length of a module category, or modularity.

Dependency tree · two levels

3 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.
