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.
Classical Schwarzschild SI family work
A conditional exact calculation on the zero-spin, zero-charge Schwarzschild slice of the selected stationary family. It is not a process, observation, evaporation model, or entropy assignment.
Statement
Assume as defined in The Axiom of Countable Choice (). Fix and choose a selected family member with SI mass parameter , angular-momentum parameter , electric-charge parameter , and zero magnetic flux. Let be the energy-valued parameter from Physical KN family work and constancy. On this Schwarzschild slice the selected outer horizon has radius , area and acceleration-unit surface gravity As varies over with the other parameters fixed, the family differentials satisfy This is a conditional identity along stationary model parameters; it does not describe an accretion process, report an observation, or assign temperature or entropy.
Facts & Assumptions
Given: The selected KN family theorem and its zero-spin, zero-charge Schwarzschild slice, fixed constants , and .
Physical KN family work and constancy: with geometric mass parameter , gives , , , , and . The physical horizon theorem's nonzero-spin-or-charge domain is completed at this point by the exact Schwarzschild supplier Exact Schwarzschild horizon data at the zero-rotation KN point.
The Axiom of Countable Choice (): means every countable family of nonempty sets has a choice function; the KN family supplier carries this convention from its geometric flux parametrization.
are fixed positive constants and ranges over ; no measured input or physical process is assumed.
Proof
The inherited premise [F2] is retained; the finite parameter calculation below makes no stronger choice. Set . By [F1], the geometric horizon radius is , so and . Also . The special case is defined for every ; it is not a limiting inference from a charged or rotating horizon.
Differentiating the explicit area function on the open interval gives Consequently This verifies the stated family differential identity exactly.
