Typos: ' two important respects.' Maybe aspects? only only

A complaint on the comment system: when you write a comment, the commented text disappears, and you have to move back and forth between the two pages. Pretty annoying.

The singular simplicial set is a natural candidate for the sort of invariant requested in Question ...

Condition requires the existence of an extension only only in the case , but demands that the extension is unique.

Comment #190 by Carles Sáez on

I'm not sure this is the appropriate place for this comment, but I cannot find any general comment section. I'm enjoying and learning a lot with this project and I wonder if there is some (prospective) table of contents for the whole project. If not, what is the expected scope? Is it expected to cover material on higher algebra, derived geometry, spectral algebraic geometry, ...?

We'll see. Baby steps.

There is a typo: "if and only it it". First "it" should be "if".

Comment #279 by Kerodon on

Yep. Thanks!

This is probably irrelevant: The 'about' page still says claims that kerodon would currently consist of two chapters only. Sorry for commenting here, but I don't think there's an option to comment at the 'about' page.

Comment #288 by Kerodon on

Good point; we'll fix this with the next update.

Comment #1488 by Daniel Gratzer on

This is a question/feature-request regarding the general project: as Kerodon grows, it might be helpful to have a change-log which is more detailed than the major revisions list. Particularly when earlier content is improved resulting in changes to existing material, rather than strict additions. For the stacks project one can see the list of commits ( so presumably gerbe supports this, but that might not make sense with Kerodon given that the repo is not public. Even a list of recently modified tags would be a pretty good solution, but I'm not sure if there's a way to do this which doesn't necessitate even more work.
