We are making a new version of the MTPro fonts, which will have Times-Italic-like characters designed into them, so that there will be no need for virtual fonts. This is a good opportunity to ask for new characters, etc.

PLEASE , IF YOU SUBMIT A REQUEST AS A GUEST, ADD AN EMAIL ADDRESS, SO THAT I CAN CONTACT YOU IF I HAVE QUESTIONS ABOUT IT!!!

My email is mikespivak@aol.com.

The following have been suggsted: :=, = with ^ accent above it,
updownarrows and downuparrows---and I think I'll add
updownharpoons, downupharpoons, upharpoons, downharpoons. Also, slanted \sum, \prod [and
presumably \coprod]. We could have \usum, \slsum, etc. to specify
upright or slanted \sum, etc., while \uoperators would normally make
\sum mean \usum, etc., while \sloperators would normally make
\sum mean \slsum, etc.

Michael,

Here are several things I came across:

1. \rightarrow with \sim on top of it (looks like \simeq but with an arrow)
2. \ast as a big math operator with limits (variable sizes: for in-text mode and display)
3. variable-length corner ( __| ) which works similar to \framebox (vertical line is variable too)
4. wide dual math accents (like \Hat{\Bar{}}, for example) with smaller gap between them

Hello Michael,

I would like to see
\& as a big math operator with limits, of variable size for text- and
display modes.

Dear Michael,

something that would be desirable in analysis
is a mean value integral "\mint". What I need
is an integral sign which is crossed horizontally
in the middle by a short bar. I have got some
TeXnical solution, but this hack only works in
the "\nolimits" case:

\newcommand{\meanbar}[1]{%
\setbox0 = \hbox{$#1 \int$}
\hbox to 0pt{%
\thinspace
\hskip 0.1\wd0
\raise 0.5\ht0
\hbox{%
\lower 0.5\dp0
\hbox{\rule{0.8\wd0}{2\linethickness}}
}%
\hss
}%
}
\newcommand{\palette}[1]{%
\mathchoice{#1 \displaystyle}%
{#1 \textstyle}%
{#1 \scriptstyle}%
{#1 \scriptscriptstyle}%
}
\newcommand{\mean}{\palette \meanbar}
\newcommand{\mint}{\mean \int}

Thank you and all the other folks from PCTeX
for developing a fairly complete mathematical
Times font family, especially for adding suitable
fonts for smaller design sizes!

Best regards,
Jens

I would suggest a symbol similar to \hbar, but for d (i.e., \dbar). This is useful in thermodynamics as an inexact differential.

1. should be simple
2. A \bigast should be OK, but do you have a sample to show how large it should be?
3. Don't know about \framebox (presumably from LaTeX? about which I
also don't know anything), but this should be doable completely in TeX, without any need for a font character.
4. Will get back to you about dual math accents later.

Should it look just like a Time &? Although \& would be a convenient name for the user, it would be simpler to implement things if it had another name, like \ampersand, or \bigampersand, or perhaps you have another name in mind.

OK, but perhaps it should be called \barint?

OK. I presume you want a regular d, not a barred partial sign ("eth").

I will add \widehatdown#1#2, which puts a \widehat on #2, but moves
it down by #1. So, for example,

\widehatdown{2pt}{\widehat{a+b+c+d+e+f+g+h}}

will look better.

Hi,

what I would like to see is the contraction operator,
for example for differential forms: \omega _| X .

:= is definitely very welcome, as would be =: and :<=>

Yes, it should look as a big & in Time font; the name I like
is \bigvarland (big alternative logical "and").

Best regards and many thanks.

Can add these. Do you mean literally :<=> or is that an abbreviation for one or more symbols?

Dear Michael,

Is it possible to make lowercase mathematical italic "z"
look as in Adobe Times PS font in my printer, with a swash?

Hi Michael,

As long as you're soliciting a wish list, here is mine:
1) blackboard bold Greek fonts, upper and lower case
2) slanted blackboard bold fonts, medium weight, upper and lower case

Thanks,

Al Freed
