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 monotone class generated by a family of sets

Definition

Let $X$ be a set and $E \subseteq P (X)$ . The monotone class generated by $E$ is

$m_{X} (E) : = ⋂ {M : M is a monotone class on X and E \subseteq M} .$

Write $m (E)$ when $X$ is clear. Its existence as a monotone class and its minimality are proved in The generated monotone class exists and is minimal ↗.

1 result within one dependency step 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.
