OK, thanks. By the way, I find that either I've to use AMS as document
type, or add "\usepackage{amsfonts}" in preamble for \mathbb to work. I'm
still using version 1.0.4, maybe in latest version I don't have to do this?
Then type \R when I want it. This comes out as a red R, which is close
enough for me :-)
Actually, the R displayed is a "hollow R" but not the R used to
represent the set of all real numbers. But it's better than nothing :)
IMO, the long-term direction for LyX needs to be to use some more capable

one of the truetype font libraries into LyX
This is of course an ideal solution, but I'm afraid this would demand
too much effort from developpers. They're programmers, not designers :(

display significantly more pleasing to the eye, and would allow
anti-aliasing as an option), and using a good unicode font (if such even
exists?).
OT: there's a TrueType Cyberstream Unicode font file, free of charge,
available. If you're using Linux with a TT font server, you could use this
font. However, this font was provided years ago, so maybe something are
missing. "Euro" is certainly missing. But personally, I prefer Microsoft's
approach in Unicode. MS provides separated fonts for every language family
and all of them constitute Unicode, instead of a single font file containing
everything. The reason is that while Times Roman or Helvetica/Arial style is
meaningful for Latin letters (or even Greek and Cyrillic), they are almost
meaningless for other language families. It's thus quite silly to provide a
"Times Roman Unicode" font file.
2) Identity symbol, usually represented as the number 1 with double
vertical stroke (just like those set symbols)
Hmm. That's not in the standard blackboard font. You'd need to try a
general latex forum for that, I'm afraid. Personally, I find a standard
'1' serves well for the identity in many contexts.
Yup, except for matrix, for example :-)
3) Symbols for "therefore" and "since", ie one dot on top and two dots
in the bottom for "therefore", two dots on top and one dot in the bottom
for "since".
.
. . for "therefore"
. .
. for "since"
Hmm. The symbosl should be \because and \since. I can't get them to
work, although I have AMS math enabled. Odd.
Are you sure it's "because" but not "therefore"? They're very
different. Please note that I'm talking about the meaning, not the exact
latex syntax because I don't know.
4) Double and triple circulation integrals. They are like the single
circulation integral, ie the integral symbol with a small circle in the
middle, but with two and three integrals symbols respectively.
You can always use the underlying LaTeX notation.
I learnt latex from written notes that my professor gave me, and
sometimes from Internet if I find any. I don't have any reference book. So
please tell me what they are.

I can't find the following symbols that I'm going to mention in the math

implement them in the future, please?

is in fact a chalk-notation for bold, and should never have made it into

in the bottom for "therefore", two dots on top and one dot in the bottom
for "since".

Re: Additional symbols
Oh, I forgot this one: 5) A square. Yes, a square and it's that simple :-) Actually, this is the space-time differentiation symbol, like the Nabla (inverted Delta) which is a space diff symbol but taken into account time derivative
