Fourier Transform Symbol
Craig Joyce
I want to generate the Fourier transform symbol (as see in Albert
Messiah's book Quantum Mechanics, and in a number of other books that
I have forgotten). I tried \mathfrak{F}, \textfrak{F}, and even \Im
after reports that it looks similar, but didn't get the effect. I'd
like to hear from someone who has used LaTeX for generating the symbol
and can share information on it with me,
thanks,
Craig

I don't know what you want, but I always use \mathcal F for this.

Take a look at the Comprehensive LaTeX Symbol List (available from CTAN)
and see if any of the fonts in the Math Alphabets table suit your needs.

Thanks for the solution. However, I just noticed that this package
makes 'fi' occurring together appear as a pound-sterling symbol Ł. for
example 'defined' appears as deŁned.
Is there a way around this? I just need the fourier transform symbol
at one place.
thanks,
Craig

FAQ. See http://www.tex.ac.uk/cgi-bin/texfaq2html?label=charshift

Yes. The mathptmx package uses RSFS as its caligraphic font (and Times
Roman as its body font, which may not be what you want). You can use
RSFS separately with \usepackage{mathrsfs}. As I replied before, take
a look at the Comprehensive LaTeX Symbol List. The RSFS version of "F"
is shown in the "Frequently Requested Symbols" list right near the
beginning of the document.

You mean: This sort of calligraphic F suits your needs?

Did you also notice that the mathptmx package is changing
all the typefaces used in the document? Did you really
want to do so?

A stupid and well-known bug of the dvips configuration
in many TeX systems.

This is a FAQ.

Instead of switching to a completely differents set of
fonts, you only need to make the particular font for the
Fourier symbol available in addition to the default ones.
Use the package mathrsfs:
\usepackage{mathrsfs}
...
\mathrsfs{F}
The package mathrsfs declares an additional math alphabet
\mathrsfs, which uses the RSFS font. The package mathptmx,
in contrast, changes all fonts used in the document and
just happens to use RSFS for \mathcal.
mathrsfs.sty can be obtained from CTAN, if it is not
supplied with your TeX system.

oops, this should read:
\usepackage{mathrsfs}
...
\mathscr{F}
^^^^^^^
sorry for the typo!

no it doesn't: that comes from your use of dvips.

tells you what you've done. in fact, with recent enough versions of
dvips, you don't have this problem ... but i'm only running that
experimentally.
