# Placing text under an entire math expression

I want to place text under an entire multivariate expression, exactly the way one is able with \underbrace, but without the brace. I want it to specifically describe the first variable in the expression, but for the text to span the entire expression. I have scoured the webs and it's all about placing text under single symbols or commands. For example, \underset, \smashoperator, and \limits can't seem to function with more than one command or variable, even when I use brackets around the command line.

I got what I wanted using this:

    \begin{align*}

\end{document}


Since you are using the command \lcurvearrownw I assumed that you were loading the MnSymbol package; this package changes many symbols.

The usual caveat that MnSymbol changes many symbols should appear. –  egreg Sep 3 '12 at 10:23
@egreg remark added. Thanks! –  Gonzalo Medina Sep 3 '12 at 13:16
Thank you @ Gonzalo, that is much simpler than my original solution and I've noted MnSymbol's potential problems. –  Brazos Wolf Sep 8 '12 at 20:04
