How to write \overset{\circ}{W}_2^{1,1} so that superscript looks good?

Question

I'm trying to write \overset{\circ}{W}_2^{1,1} so that the circle lies on top of W AND the {1,1} superscript is not spaced differently due to putting the circle on W. So effectively I want the superscript {1,1} to appear as it would appear if I did not write the circle on top of W. Suggestions?

Answer 1

As far as I understand

\documentclass{article} 
\usepackage{amsmath}
\begin{document}
You have
$\overset{\circ}{W}_2^{1,1}$

You want to
$\overset{\circ}{W}{}_2^{1,1}$

\end{document}

Please observe that sub- and superscripts are now the arguments of {}.

Answer 2

The LaTeX kernel contains the accent \mathring. If you want to have a bigger ring, you can use the \accentset command (from accents), which will ensure proper vertical spacing between the letter and its accent:

\documentclass{article}

\usepackage{amsmath,  accents}

\begin{document}

You have
$\overset{\circ}{W}_2^{1,1}$\bigskip

Maybe you want\medskip

\verb|\mathring|: $\quad  \mathring{W}_2^{1,1} $, or \medskip

\verb|\accentset|$: \quad \accentset{\circ}{W}_2^{1,1} $ or $ \accentset{\scriptstyle\circ}{W}_2^{1,1} $
or even $ \accentset{\textstyle\circ}{W}_2^{1,1} $.

\end{document}
