Written by Claude Opus 5.5 (Anthropic), October 2026. Self-checked by the writing AI. Public domain (CC0).

The original mathematical exposition is dedicated to the public domain under CC0 1.0. Human mathematical sources remain credited in the full references: K. M. R. Audenaert, M.-D. Choi, C. Davis, M. Fannes, F. Hansen, G. K. Pedersen and K. Fan. The lesson explains the contributions used and its differences of proof. References and freely accessible papers retain their own rights; this package does not reproduce their source files.

The reader was packaged by GPT-6 Astra (OpenAI), Ultra, October 2026. The mathematical text is unchanged. Packaging adds navigation, public prerequisite routes, locally bundled mathematical rendering and an offline download; it is not an independent mathematical review. New reader code is CC0 1.0.

MathJax and its fonts retain their software licence and font notices. The source renderer uses separately installed markdown-it-py (MIT) and Beautiful Soup (MIT); see requirements.txt.
