Topic: old documents on fibered categories available by Bènabou,...

Thomas Streicher has made available several scans of documents on fibered categories by the authors Bénabou, Celeyrette, and Moens, as announced in the following message also to appear on the categories mailing list:

After getting permission from Jean Bénabou's son for doing so I have
made copies of some of his most influential unpublished texts on
fibered categories available on my home page under
https://www2.mathematik.tu-darmstadt.de/~streicher/FibCatTexts/

In 2 folders at the same place you find copies of the Theses of Celeyrette and Moens. The first one was directed by Jean himself and the second heavily influenced by Jean's 1980 course.

The copies are partly of moderate quality but readable with a bit of good will. Would be great to have them typed within TAC Reprints series!

Jean's work was very influential but not easily available. Hope these copies make it easier for younger people to form their own opinion about seminal work overshadowed by controversies in the past...

I am grateful to Jonathan Weinberger for helping me to prepare the copies.

Thomas Streicher

Can they also be made available in djvu format? Might make for smaller files

Not originally, I think

I might try and see if it's straightforward to convert them with reasonable quality

I have the files anyway, but they are pretty big. Compare for instance the old pdf scan of Pursuing Stacks (which was a whopper) to the djvu version.

^ it's the right time and place to spam about this initiative!

Great initiative, the Texromancers! For fun I would like to have the contrary: a TeX package that makes texts look like the old Springer lecture notes, with their uneven type writer font and handwritten greek letters...

Makes category theory feel more raw and wild, still untamed, that's for sure...

I unironically thought about this with @Paolo Brasolin when we were young and rogue.

I wanted to mimick the particular style of papers written with an IBM Selectric typewriter.

Do you have an example of such a paper?

Here's a page from LNM897, about the Ω\Omega-rule. For the LNM, authors had to submit a “camera-ready copy”, and I'm not an expert in typewriters, so I can't say for sure which machine was used, but the use of subscripts and special characters suggests the Selectric. (Still some things had to be added by hand.) Someone can correct me if I'm wrong: Omega1rule.jpg

Faisceaux Pervers and in general the first issues of Astérisque were written with a Selectric iirc
