I have the following Latexcode:

\begin{equation}
\mathscr{G} = A_{polygon} - \sum \limits_{C \in \Xi} A(C)
\end{equation}

However, the sum index looks bad in my eyes, as the "is element of" sign is a little lower than the other two letters. It looks badly aligned. Is there a way to fix this? I don't want to change to to smaller case letters as I have a convention for letter cases in my document.

edit: I've added a picture

Picture of the rendered latexcode.

I'd like the element sign to be above the red line i.e. vertically centered with C and Ξ.

    That is basically just how it looks in the standard font. It looks differently in other fonts. BTW: please remember to post full minimal examples instead of sniplets. Not everyone knows where \mathscr comes from – daleif Aug 24 '16 at 9:33
  • I should be \mathscr{G} = A_{\mathrm{polygon}} - \sum_{C \in \Xi} A(C), but, in any case, I don't think it looks bad. – Manuel Aug 24 '16 at 9:44
  • @JnxF. no please don't promote this, \text is for textual comments, polygon is not a comment but an index. Plus if the textual context is italic then so is the outout from \text which is not what you want here. – daleif Aug 24 '16 at 9:54
  • Thank you for your comments. I've added an image to make it more cleared what I want. – infinitezero Aug 24 '16 at 11:34

While the "does not look good" is in my opinion quite a matter of taste, you can easily define a new version by putting the \in in a box and raising the box by its depth:

\documentclass{article} 

\makeatletter
\newcommand*{\myin}{\mathrel{\mathpalette\@myin\relax}}
\def\@myin#1#2{{\setbox0=\hbox{\m@th$#1\in$}\raise\dp0\box0}}
\makeatother

\begin{document}                      

Original: $A\in B$, $\displaystyle\sum_{A\in B}$
New: $A\myin B$, $\displaystyle\sum_{A\myin B}$

\end{document}

enter image description here

  • Of course, looks are always a matter of taste. Thank you for fulfilling my expectations :-) I'd upvote but I'm still collecting the required rep. – infinitezero Aug 24 '16 at 13:32
