The chapter provides detailed derivations, historical perspectives,
computational remarks, and 18 exercises with worked solutions. Native
diagrams and tables are incorporated into the single LaTeX source.

The chapter has been submitted to arXiv; the public identifier is pending.
This GitHub release is a versioned distribution of the repository materials,
not an assertion of arXiv acceptance or a journal publication.

Reuse for research and teaching

These materials are shared to support research and teaching. The original
text, diagrams and lecture materials may be reused and adapted under the
repository's GNU GPL v3 licence. Please credit Pierre-François Loos and cite
the chapter; citation metadata is provided in CITATION.cff.

Third-party images, reproduced material and portrait adaptations remain
subject to the individual licences and permissions recorded in the chapter
and chapter/records/. Permission-pending notices are retained and are not
grants of permission. The invitation to reuse original material does not
override those third-party terms.

Verification and reproduction

The chapter compiles with pdfLaTeX/latexmk. Reference and notation checks,
figure/table callouts, graphic checksums, exercise pairing, and independent
HF/integral/MP2 numerical checks have been verified. The scientific chapter
source and lecture sources are unchanged by the GitHub release setup.

Build instructions and scientific illustration provenance are included in
the repository. GitHub's automatically generated source archives provide
the complete tagged repository, including lecture sources and verification
scripts; the attached chapter source ZIP is the smaller standalone bundle.
