comment Symbolic solution(s) to generalized Heat equation
@chris Upping the dimensions is one possibility, and automating the Green's function is another. Both can be automated to some extent - which is to say that there is definitely room for Wolfram to add some functionality. But yes, it should be possible for us to do some of their work for them... with the caveat that it will probably break in less standard cases (e.g., elliptical coordinates are already much harder).

Great analysis and solution for the main issue - it also works for FrameLabel where the same issue appeared.

What you observed also holds for Hold in the same context, so you must have hit the nail on the head. I think this cannot have been done intentionally - it makes no sense.

comment HoldForm doesn't hold form
I suspected that one could find a working character encoding, but of course I would like to keep the default encoding. Anyway, thanks for that find, too! In terms of using Inactive[Set], I would then probably not bother and rewrite everything with FormBoxes. But the fact that Hold has the same issue as HoldForm in AxesLabel really worries me.

That's a valuable observation, thanks!

@m_goldberg Will do. There are no change notes for HoldForm in the docs, so I would think this is a regression.

comment HoldForm doesn't hold form
Thanks, that's definitely a workaround in some cases. But unfortunately it doesn't solve the issue with my first Plot example, where I used the (admittedly contrived) label HoldForm[InputForm[E = 1]] to get E instead of the double-struck letter.

comment Using a function name instead of its definition in AxesLabel
@BenAllgeier I also see this problem, and I think it's a bug in version 10. I'm currently mostly using version 8 because I want to wait until the bugs are fixed. In the meantime, maybe you can instead use my answer here, until we figure out what's wrong with HoldForm. I'll update this when I know more...

Perhaps this Scientific American article is of interest. If you do want fast note taking, I would recommend LyX.

comment Checking Calogero-Moser eigenfunction
The sums aren't infinite, they are limited by the quantum numbers p, q, r. Anyway, I don't know a quick answer because I'd have to define your Hamiltonian first. The trick I use in the linked answer relies on Solve to do some of the work of simplifying and isolating the eigenvalue, which in general works much better than the naive approach of dividing HJ by J. But even this approach may fail for really complicated expressions like yours, unfortunately.
