Reposted by Christopher HanusaRichard Elwes @richardelwes.bsky.social · 09/10/2026Here's a story I was forwarded about how AI-usage in mathematics helped bring together a team of mathematicians to broaden human understanding.

The paper referred to is here: arxiv.org/abs/2610.10144 1/4arxiv.orgHigher Fomin-Kirillov algebras are infinite-dimensionalWe show that the Fomin--Kirillov algebras $FK_n$ are infinite-dimensional for $n\geq6$.

Christopher Hanusa @mathzorro.bsky.social · 09/10/2026And here's the picture for terminal 1: www.aeroport-roissy-cdg.com/images/plan-... You can't get from one side to another once you go to departure so it's important to distinguish between them. 000
Christopher Hanusa @mathzorro.bsky.social · 09/10/2026I think they correspond to different passport regimes. This link shows why current terminal 3 (new terminal 2) has two letters Schengen non-Schengen: es.maps-paris.com/img/0/cdg-te... 200
Christopher Hanusa @mathzorro.bsky.social · 09/10/2026Terminal 1 has a number of wings, looking like they are designated U-Z in that list. 100
Christopher Hanusa @mathzorro.bsky.social · 09/10/2026Are they the numbers for the physical locations for parking aircraft? My guess is that they want to align these two sets of numbers. 100
Christopher Hanusa @mathzorro.bsky.social · 09/10/2026My guess is that the goal is to fix the mess here www.ifatc.org/gates?code=L... You can see that multiple terminals have gates that start with the same letters!ifatc.orgIFATC Info - Airport Gates 100
Christopher Hanusa @mathzorro.bsky.social · 09/10/2026So the buildings are the terminals, broken down into one or more departure halls, which correspond to some number of gates. 200
Christopher Hanusa @mathzorro.bsky.social · 09/10/2026Yes I see that. The FAQ has more information. Yes, from 16 March 2027, boarding gates will also adopt a new numbering system with a letter and two digits to simplify orientation in the terminal. Each boarding area will be represented by a unique letter. 100

Christopher Hanusa @mathzorro.bsky.social · 09/10/2026Terminals 1 and 3 are very much satellite terminals away from the main area, so it makes sense that they are the new 1 and 2. And I expect that any future growth would be centered around the current terminal 2. 100
Christopher Hanusa @mathzorro.bsky.social · 09/10/2026A porte d'embarquement is a gate, not a lounge, which is part of the confusion. Actually the new terminal numbering makes a lot of sense. 2A and 2C have been joined at the hip and so are 2B and 2D. They are also in the same direction from the TGV station / growing surface transit hub. 100
Reposted by Christopher HanusaDoug Gordon @brooklynspoke.bsky.social · 08/10/2026As this excellent story notes, the city probably should reconsider Lyft's monopoly and allow a dockless bikes such as Lime.
