Here I would like to list some topics on which I have written some thoughts. Eventually these might be used in Wikipedia if I can find references, since original research is not allowed. Please let me know if you have any suggestions.
- /Fourier transform (Nov. 2006)
- /An Euler-Maclaurin-like formula (see also this material by User:HenningThielemann on the digamma function)
- /A coordinate system for an expanding universe
