An evolving theoretical chemistry notebook whose current manuscript covers introductory and advanced quantum chemistry, Fourier transform, and a miscellaneous section, while the repository structure also keeps draft material for additional topics such as DMET and other extensions.

A self-written set of functional analysis notes organized around metric and topological spaces, normed linear spaces, bounded linear operators, Hilbert spaces, operator spectra, and exercises, intended as a mathematical foundation companion to the broader quantum chemistry note series.

A carefully transcribed and lightly annotated edition of Mathematics in Quantum Chemistry, covering an introduction, orthogonal functions, linear algebra, classical mechanics, and a concluding summary for readers approaching quantum chemistry from the mathematical side.
