I've got the following problem:
I want to set the letter "W" atop a "\vdash", like here:
I've tried to get this result with \atop, \stackrel, and \above, but didn't get the wished result. All these put the W completely over the vdash:
How can I get the first result?
PS: here is a sample file:
\documentclass{article}
\begin{document}
$A \stackrel{W}{\vdash} x$
\end{document}
