@JonathanBeardsley it's not working here either

@HarryGindi Is this the state-of-the-art in the justification of the Appendix in Gaitsgory-Rozenblyum? Would it get close to filling all the gaps? I am writing a paper using their correspondence machinery (stating carefully that it is conditional on their results!) and I would be very happy if that saga was finally complete.

@HarryGindi I'd say mostly for the dualities available in $\Theta_2$-sets, but as far as the monoidal structure itself that was already available from Verity's work

@SimonPepinLehalleur As Edoardo said, a lot of this stuff was already developed for complicial sets, and the recent work of Gagna-Harpaz-Lanari more or less gives you a way to apply this in concert with Lurie's (un)straightening theorem by completing the equivalence between 2-trivial complicial sets and scaled simplicial sets

However, Yuki's paper is also excellent and has a bunch of interesting (∞,2)-categorical combinatorics. I personally prefer the Θ-type models to complicial sets, mainly because the representable objects are all fibrant and represent the obvious elementary operations of n-category theory. I was very excited to see this come out, but Gagna-Harpaz-Lanari does give you, at least right now, a better toolbox.

@HarryGindi what's not working

The link to the Zulip?

@JonathanBeardsley yeah it says I need an invitation.

Did you read the conversation following my initial posting of the link

Others had that problem but seemed to resolve it.

@JonathanBeardsley Did they resolve it or give up?

@HarryGindi People seemed satisfied with the answer (I did not try it)

It was resolved.

Click on the twitter link.

Weird

ok, worked

Just wanted to check it out, don't know if it's for me.

There's not much \infty-category stuff happening there.

I've been learning a bit about algebraic theories and their relationship to operads.

Did you read Clark's paper?

There's also some interesting discussions happening around cybernetics and semiotics.

Which paper?

arxiv.org/abs/1302.5756

Operator categories in this paper are more or less algebraic theories

I have not read it in detail, but I am pretty familiar with it.

Well, if you're looking into the relationship between algebraic theories and ∞-operads, this basically the one-stop-shop

I read it a long time ago, so I don't know exactly which algebraic theories correspond to ∞-operads, but iirc this gives a framework to change back and forth between them

I see. Well yeah I'm not really looking to create more work for myself in interpreting something. I'm more just having things explained to me by logicians, which is nice.

@HarryGindi Great. So is someone who understands Verity+Gagna-Harpaz-Lanari well going to write down and publish somewhere "Thm: the results in [GR,Appendix.] are true"? That would be really a public service for the poor end-users like me.
