bigger \sum

bigger \sum

[Torben Knudsen]

Can I make a bigger \sum manually or better, is there a adaptive
version like \left( ?

afaik the size of the sum sign is at least depending on the environment. 
it is small in $...$, bigger in math-environment and 
eqnarray-environment. maybe it's enough if you change the environment...

Either make the font used for this face bigger or use another font  
for this face that has such a larger upper-case Sigma. Both methods  
will change all text (all characters) displayed in that face.

Thanks for the suggestions.  However, I think that there should be
something similar to \left(.  Maybe someone will make such a
contribution some day.  Until then I will use the suggestions given to
me so far.

Have you found preview in AUCTeX? Does it deliver what you are missing?

I think that what Knudsen is after is a variable size version of the
LaTeX \sum command, which, like \left( \right), resizes to fit the
stuff inside.

This really isn't the right newsgroup for help, as it's a LaTeX
question rather than an emacs one. Have you tried eg the texhax
mailing list?

P.S. I've not tried it, but I presume "\left\sum <stuff> \right."
doesn't work.

In LaTeX you have options to make a glyph bigger on screen and on  
paper. This feature is not provided in GNU Emacs since it uses the  
glyphs as they come out of a font in the size of the text used (set)  
with this font. Options can be to create a fontset that uses for ∑  
the glyph from another font (or same font at larger size) or it's  
associated with a particular face that takes the bigger glyph from  
another font.

My final (we had some private eMail conversation) recommendation for  
Torben was to apply the preview option of AUCTeX on (some) formulas  
that they look as they should (in his opinion) – at least this will  
show that TeX won't make the mistake of choosing too small symbols.  
Another option would be to use a specialised TeX editor like TeXmacs  
or Lyx that has more graphical capabilities ...
