Todo: add more proofs of this result.

For some reason the xymatrixes were causing errors so I had to comment them out to submit. Here is an example error:

An error occurred when running pdflatex on the following diagram. \xymatrix@=5em{e \ar[r]^\gamma \ar[dr]_{\gamma’} & GFc \ar[d]^{Gf} \ & GFc’} The error was: Timed out

How can I fix this?

For the xymatrix to display, they must not be enclosed by any other environment and the delimiters must be aligned to the far left.

(I was going to fix it, but, since last night, all attempts to submit tikzcd or xymatrix to the $n$Lab time out.)

Now the xymatrix is rendering. Also made the author links come out and added publication data.

I just tried to do some typo fixes, but xymatrix is timing out again. Any idea what's happening?

Just tried tikzcd instead...it still timed out. I know that it is not just a typo because I copied one of the example tikzcds from https://ncatlab.org/nlab/show/HowTo and that made it time out. Any suggestions?

According to Richard here, the server has apparently reached the point where it can’t handle the size of the $n$Lab anymore, and we need to wait for Richard to, thankfully, migrate us to a better server.

I think editing this page may be triggering the problems, as it is deeply nested in the rest of the nLab, so it may be best to hold off for a while.
