The source files below are often literate programs: a single file is

All the notes are thus built by a simple
For image-heavy documents, the html output is recommended because sets of
related images are collected into galleries (the pdf file will have many
pages with one image on each).

Generalizations of Fourier analyisis,
We explain some common generalizations of Fourier analysis: sampling
theory, distribution theory, pontryagin duality and spectral geometry.
The part on spectral theory is shared with the article about PDE on
manifolds (needs some editing yet)
