Math & Science ⇒ dot below a symbol

[acire]

I would like to place a dot under a symbol in math modes.
Something like underline or utilde, but with a simple dot.
\d will not do, since this is only defined in text modes.

All suggestions are welcome.

Many thanks in advance.

Hi, Erica

you could try using \underset from amsmath or \underaccent from accents (I recommend this last option); a little example:

Code: Select all

\documentclass{article}
\usepackage{amsmath}
\usepackage{accents}

\begin{document}

$\underset{\cdot}{x}$

$\underaccent{\cdot}{x}$

\end{document}

Thanks.
That was helpful
