Zur Quantenmechanik der Stoßvorgänge

Max Born’s 1926 paper supplies the historical probability interpretation of quantum transition amplitudes. It is recorded as context for the projection weight formalized in D5/S3/Quantum/FiniteDimensional, not as a direct source for the modern density-matrix trace notation.

The repository theorem does not derive the rank-one pure-state modulus-square formula, the Born rule from an observer ledger, or any numerical spectral-pruning or quartic-pricing claim. Those parts of the source residual remain unresolved.

  • 2026-07-17: Queried Born rule density matrix trace rho P historical source. Results linked the modern trace formula to the Born probability framework, but did not justify attributing the exact Lean statement verbatim to the 1926 paper; the Scribe provenance therefore uses Gleason directly and cites this note as context only.
