I would like to have have an equation like a \in \overset{\sim}{\mathcal{G}}, where the vertical spacing between G and \sim is lessened but where horizontal spacing between G and other elements in the equation is maintained.

I've tried using combinations of \stackrel and \smash, which work fine for vertical spacing but not the horizontal spacing.

    Why not just \widetilde, e.g. \documentclass{article} \usepackage{amsmath} \begin{document} \[a \in \widetilde{\mathcal{G}}\] \end{document}?

  • This is a good alternative! Though it's not the optimal aesthetic I'm hoping to achieve. Dec 7 '19 at 1:07

    Can you perhaps add a sketch that explains how that should look like in detail?

You can use the accents package:

\documentclass{article}

\usepackage{amsmath}
\usepackage{accents}

\begin{document}


\[ a \in \accentset{{\sim}}{\mathcal{G}} \]

\[ a \in \accentset{{\scriptstyle\sim}}{\mathcal{G}} \]

\end{document} 

enter image description here
