Better script fonts for maths

The font selected by \mathcal is the only script font “built in”. However, there are other useful calligraphic fonts included with modern TeX distributions.

- Euler The eucal package (part of most sensible TeX

distributions; the fonts are part of the AMS font set) gives
a slightly curlier font than the default. The package changes the
font that is selected by ''\mathcal''.

Type 1 versions of the fonts are available in the AMS fonts
distribution.

- mathabx The mathabx bundle provides calligraphic

letters (in both upper and lower case); the fonts were developed in
MetaFont, but a version in Adobe Type 1 format is available.  The
bundle's documentation offers a series of comparisons of its
calligraphic set with Computer Modern's (both regular mathematical
and calligraphic letters); the difference are not large.

- mnsymbol The mnsymbol bundle provides (among many

other symbols) a set of calligraphic letters, though (again) they're
rather similar to the default Computer Modern set.

- RSFS The mathrsfs package uses a really fancy script

font (the name stands for "Ralph Smith's Formal Script") which is
already part of most modern TeX distributions (Type 1 versions of
the font are also provided, courtesy of Taco Hoekwater).  The package
creates a new command ''\mathscr''.

- RSFSO The bundle rsfso provides a less dramatically

oblique version of the RSFS fonts; the result proves quite
pleasing --- similar to the effect of the the (commercial) script
font in the Adobe Mathematical Pi collection.

- Zapf Chancery is the standard PostScript calligraphic font. There

is no package but you can easily make it available by means of the
command

\DeclareMathAlphabet{\mathscr}{OT1}{pzc}{m}{it}

in your preamble.  You may find the font rather too big; if so, you
can use a scaled version of it like this:

\DeclareFontFamily{OT1}{pzc}{}
\DeclareFontShape{OT1}{pzc}{m}{it}{<-> s * [0.900] pzcmi7t}{}
\DeclareMathAlphabet{\mathscr}{OT1}{pzc}{m}{it}

Adobe Zapf Chancery (which the above examples use) is distributed in
any but the most basic PostScript printers.  A substantially identical
font (to the extent that the same metrics may be used) is
available from URW, called URW Chancery L: it is distributed
as part of the "URW base35" bundle; the
[[ctanpkg>urwchancal|urwchancal]] package (which includes virtual fonts to tweak
appearance) provides for its use as a calligraphic font.

The TeX Gyre font family also includes a Chancery replacement,
''Chorus''; use it with [[ctanpkg>tex-gyre|tgchorus]] (and ignore the
complaints about needing to change font shape).

Examples of the available styles are linked from the packages' catalogue entries.
