COS Method
Quadratic-form probability calculations, tail accuracy, and numerical evidence.
Completion: Reading edition complete · Lean: Selected results recorded · Confidence: Recorded formal evidence
Before you start
Suggested background: Begin with the introduction and glossary. Then use the volume's own definitions to identify the background needed for its subject.
Recorded results and limits: Closing 138-page publication with a finite Gram/enclosure Lean companion. Full numerical correctness is outside the official companion.
Remaining work: Keep the official monograph stable and route end-to-end numerical proof work to the separate continuation.
The background advice is an editorial starting point. The work itself states its prerequisites and hypotheses.
