    I added a reference to the notes

    to relevant pages like quasi-category, (infinity,1)-topos, (infinity,1)-category of (infinity,1)-sheaves.

    Under “related entries” there was a requested link to “test topos”. I have removed that, as the page doesn’t exist and the link was broken and looked bad.

    Incidentally, Google gives me a single relevant hit for “test topos”, and that’s just an informal usage in passing: by Duskin (2013) on p. 7 here.

    Of course, if anyone goes and creates a page for test toposes now that cites Denis-Charles, then let’s put the pointer back.

  1. Cisinski has, or at least had, an unpublished but quite long note on test topoi on his webpage. This is the only reference I’m aware of.

    Thanks. But who says “test topos”? (Or topos test, for that matter?) The document you point to talks, besides catégories test, about localisateur test and catégorie test locale.

  2. The introduction of Cisinki’s main work on test categories, Les préfaisceaux…, contains various remarks on test topoi (explicitly mentioned). Some of the things he mentions, such as the relationship to internal presheaves, are discussed in the unpublished note I linked to.

    Ah, there you go. Thanks. I’ll add a pointer to that, then.

    Add redirect from Cisinski. Cosmetic edits (accented characters, spacing).

  3. Added new english Wikipedia article. The german Wikipedia article is now also available.

    The english Wikipedia wants more reliable secondary sources. I’d be happy about suggestions.
