revised Evaluation of Hankel determinants for the reverse Bessel polynomials
I discovered that the polynomials are the reverse Bessel polynomials.

comment Evaluation of Hankel determinants for the reverse Bessel polynomials
@NicolasMalebranche I have now: it's a good read! I had looked at it before, but the reason I was put off using Theorem 11 is that each b_i is a rational function that seems to be far more complicated than the polynomial H_i, and I don't see an obvious way that would help me.

comment Is this graph of reciprocal power means always convex?
If you take a large $N$, say $100$, and $n=N-1$ with $p=[1/N,1/N,\dots,1/N,2/N]$ then you get something that looks very non-convex.

comment How to draw knots with Latex?
In paragraph 2, where you say "xy-pic", do you mean "xfig"?

comment Representability of finite metric spaces
This is just the Kuratowski embedding or $L_\infty$ embedding alluded to in Tom Leinster's and David Eppstein's comments. (In enriched category theory terms this is the Yoneda embedding.) I would say that there is nothing specifically tropical being used here.

comment How do you see that higher genus surfaces are not homogeneous?
Thanks for the useful replies everyone. The key pointers for me were the terms "geodesics" and "Weierstrass points". I've now stitched together much better intuition from what people have said.

comment How to correct an error in a submitted paper?
You think that's disastrous? I had a referee reject a completely different paper of mine! I assume they must have downloaded a random paper of mine off the arxiv. They wrote quite a scathing rejection of the paper without being very specific - fortunately I noticed that they alluded to certain things that were not mentioned in the submitted paper so I was able to point this out to the editor. (And it all ended happily for both papers.)

comment Using TikZ in papers
I had problems with the arxiv not having an up-to-date version of pgf-plots. The arxiv people said "pgf/tikz simply develops at too fast of a pace for us to keep up." It was suggested that I use the work-around I mention further down this page.

I don't understand your question. Where might I be assuming that?
