A: Automatic groups - recent progress

Ian AgolI'm not an expert in the area, but here's a few highlights: Bridson distinguished automatic and combable groups. Burger and Mozes found examples of biautomatic simple groups. Mapping class groups were originally shown to be automatic by Mosher. Recently, Hamenstadt has shown that they are biautom...

The link given here seems to be dead: "McCammond's survey for an update on open problems." And I did not get the pdf file from the Wayback Machine either. Is the paper in question perhaps Algorithms, Dehn Functions and Automatic Groups? — Martin Sleziak 2 mins ago
I don't see any posts with such links on Mathematics: math.stackexchange.com/…

dead-link I have fixed this instance, but there are 16 more posts linking to topology.auburn.edu.

Q: Does uniform continuity of bounded continuous functions implies the same for all continuous functions on a uniform space?

JaveRecently I came to know about Atsuji space from the paper1. A metric space $X$ is called an Atsuji space if every real-valued continuous function on $X$ is uniformly continuous. Strikingly I have found in the above paper that, $X$ is an Atsuji space if and only if every bounded real-valued contin...

A: Can the mass-replacement tool also replace and remove?

GlorfindelIt's just a simple Find & Replace tool which (AFAIK) doesn't support wildcards. In that case, that means the operation needs to be performed once for every individual PlanetMath page that is being linked to (because the .html needs to be removed). I'll wait for a staff member to confirm this, but...

It was in connection with some other type of links, but still, I will point out this part:
> ... but it's a trivial change for my Broken Link Repairer script, which does have the disadvantages that 1) it bumps the post and 2) on some sites (I saw a couple of Physics hits), it can only suggest edits. It has the advantages of checking whether the new link actually works and repairing other broken links (if any).
Maybe also the replacement of some links (those where arxiv.org/abs/math/ does work) could be automated in this way?
However, I am not sure whether the script would be able to detect that the link is worng.
Let's take this as an example:
Another weird data point. I think the link front.math.ucdavis.edu/9712.5188 should point to arxiv.org/abs/q-alg/9712048 — David Roberts Oct 5 '21 at 3:03
The links arxiv.org/abs/q-alg/9712048 works. The link obtained by the naive replacement does not work: arxiv.org/abs/math/9712188 - but it does not return 404. (It returns a page saying: "Article math/9712188 in the Mathematics archive not found".)

@MartinSleziak Hmm, that looks that’s it. It looks like they took the wiki down, and it resides here: sites.google.com/a/scu.edu/rscott/pggt You need permission to access the google drive, so I’m waiting to be granted access. — Ian Agol 2 hours ago
