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.
Local regular-center central-pressure family
Example
Let have units , let be dimensionless, and prescribe the smooth positive state relation for . Fix and let the central pressure range be . This is a mathematical equation-of-state example, not an observational stellar model.
Facts & Assumptions
Given: The state relation, the compact interval , a fixed central lapse value , and inherited from The Axiom of Countable Choice ().
For every smooth positive on an open positive pressure interval and compact central pressure interval contained in it with a positive margin, Regular-center TOV local existence and dependence supplies a common , the unique integral-equation profiles in the stated pressure ball, a Cartesian center, continuous dependence on , and continuation only within a compact subset where , , and .
The geometric supplier chain uses exactly as defined in The Axiom of Countable Choice (), with no full Axiom of Choice.
Verification
The map is and positive on . Since , any gives the required closed pressure margin around inside .
Apply [F1] under [A1] with this and . There is one radius valid for every , and the corresponding solutions depend continuously on in the uniform norm; they satisfy , , and have positive lapse and .
Remarks
This is local existence and parameter dependence for the stated mathematical system. No surface at , global compactness bound, empirical equation of state, or dynamical stability conclusion follows.
