    There is no link on the page to the thing being described, is that right/intended?

    @Urs It seems to be a tease

    The proof assistant is still under development, and is not yet released for general use. It can be considered a successor to the existing proof assistant Globular, which allows the construction of formal proofs in a strictly associative and unital model of 4-categories.

    Presumably the link will be something like, but not yet released.

    Okay, thanks. Of course I am sympathetic to the cause, but let’s invest a minimum of energy to make this more of an actual nLab page.

    I am on my phone right now, maybe somebody can help me:

    First, there must exist some preliminary resource that the page can point to. If nothing else let’s add pointer to Dorn’s talk slides on associative n-categories that Google knows about.

    Then, let’s cross link with our page proof assistant.

    Finally also the page associative n-category is currently a little unusual for the nLab in its emphasis of announcement over content. Maybe somebody could help Jamie to edit this a little, cross-link with related entries, add references, etc.

    okay, I have linked back to here from proof assistant and added pointer to the following references:

    I suggest the links to contibutors’s names in the entry should all point to their corresponding nnLab entries, for link stability, but I won’t implement that, or not now anyways

    Thanks for these edits. The intention is not to tease but to get something in place for the release of the proof assistant, hopefully later this week.

    Thanks for adding this.

    I’d suggest the main page should have some pointer offering indication on what’s going on, maybe a pointer to the Overview of Functionality that you just added.

    Significant updates to the tool description. @Urs: yes, I will add such a link soon.

    added pointer to:

    Incidentally, most of the references listed do mention (though not the first ones, which seem to be included just as background on associative nn-categories?) but none of the references seems to be really about as such.

    The main link given

    does not work for me: it gives me the “Potential Security Risk Ahead”-thing. I am sure somebody will tell me that I can work around this using a VPN or something, but is there a link which would just work?

    The one alterntive (?) I could find is

    which I have added. But as with most github pages, this doesn’t serve as a landing page for outsiders.
