Thanks to Egbert for starting this! (We had been discussing behind the scenes).
I have now added redirects and changed capitalization in order to make the last three hyperlinks come out properly:
The second and third of these would deserve page of their own. If so, just remove the redirect and create the dedicated page.
The spam detector of the nlab prevents me from making further edits. What can I do about this?
Try to add smaller pieces at a time. If all fails, post the code to the nForum here and I can insert it.
added hyperlinking to a few more of the technical terms (such as type theory, homotopy theory and Agda)
Thanks so much!
And I figured it out with the smaller edits :)
I tried to include the links in a way that doesn’t suggest that the pdf is what the book actually will look like (because these course notes are quite old).
Might you (or anyone reading here) have 5 minutes to give “Univalent Foundations for Mathematics” a little entry of its own, with a sentence on the basic idea? (So that it does not just redirect to the HoTT book.)
And while we are at it, let’s rename to “Rezk-Lurie-Voevodksy’s univalent foundations” – because, apart from the inventive terminology, the observation of univalent universes first appears in Jacob’s HTT 6.1.6 (published 2009), where it is attributed to private conversation with Charles. Voevodsky’s first note on it seems to be from 2010.
The latter is AFAIK something that Voevodsky started for foundational reasons, whilst the former is typically attributed to Voevodsky
That’s a telling slip of tongue there ;-)
To the guest at 17: the textbook isn’t published yet, but Egbert Rijke did release another preprint here.
Not sure where this link was intended to point, but the entry Introduction to Homotopy Type Theory (which #17 is referring to) lists several links to preprint versions.
Urs, this preprint was only released on September 2021 as said in the pdf file itself, so isn’t actually linked in the article.
I still don’t know which preprint you mean, as the link in your #18 is broken! (Maybe I should have said this more explicitly in #19. Please check the link and let us know where you are pointing us to.)
It’s a link to a pdf on the HoTT Zulip, this is the thread where it is.
A new draft of this textbook has been put out to the public in the HoTTEST Summer School 2022’s github repo
There are some changes from the chapter listing on this article.
The changes in the section titles are as follows:
There are no changes to any of the section titles in chapter 3.
Just out of interest: This is changes with respect to what?
The current contents listed on the nLab’s article for this textbook.
Oh, I see. Thanks, and thanks to Carlo for making the edits (here).
I have gone through it and adjusted/fixed the formatting of the list of book sections a little.
Notice that, for better or worse, our Instiki wiki software here has the “feature” that it generates automatic numberings whenever it senses that the user is typing a numbered list.
On the positive side this means that you can make numbered lists by typing
1. first point
1. second point
1. third
etc. and be ensured that the numbering always comes out right, even if later somebody adds an item in between the previous first and second point, say.
On the downside it means that if you mean to insist to not start counting at 1, say by typing
15. this list starts with item 15, because it means to continue a previous list
16. and so its second item wants to be numbered 16
17. and so on
then Instiki will override this decision and start numbering from 1, after all.
To work around this in order to bring out your (Carlo’s) intended list, I have resorted to a little hack and made indented numbered items by typing
$\;\;\;15.$
$\;\;\;16.$
$\;\;\;17.$
etc. This hack works here (only) because the list items don’t wrap around lines.
