Text Formatting ⇒ Complement in Latex

[helllo]

Hi guys,

I'm trying to type the intersection of complement of sets (with a "c" on the top right) in latex but it doesn't work well with the following:

Code: Select all

$\cap_{i \in I} ^{c}G_i

any suggestions?

Thanks!

What is not working well in your opinion? Be more precise in your problem description.

Hmm ... I'm not sure how to explain it but basically the "c" is closer to the intersection than to the G_i's if that makes sense.

So, if you want some kind of left superscript, have a look at the \prescript command from the mathtools package.

Or use the leftidx package. Don't put the c as superscript to the intersection, it's logically wrong. You may consider to use an upright c instead of an italic c which looks like a variable.

Code: Select all

\documentclass{article}
\usepackage{leftidx}
\begin{document}
$\cap_{i \in I}\leftidx{^{\mathrm{c}}}{G}{_i}$
\end{document}

Ok thanks!
