Consider the following excerpt:

enter image description here

The code is below:

\begin{eqnarray*}
|\xi|\geq R&\pause\Rightarrow &|a(x, \xi)|\geq C|\xi|^m\\
&\pause\overset{|\xi|\geq 1, m\geq 0}\geq & \frac{C}{2^m}(1+|\xi|)^m\\
&\pause =& C (1+|\xi|)^m.
\end{eqnarray*}

Is there a way to make the code over the \geq (inside \overset) to look smaller?

I have tried the code \tiny but it didn't work.

Thanks

LaTeX font sizes like \tiny can not be used in math mode however the Tex primitive commands \scriptstyle and \scriptscriptstyle are available to choose the size and style normally used in superscripts and superscripts of superscripts respectively. You probably want \scriptscriptstyle here.

Unrelated but eqnarray isn't the high point of the latex format. The align environment from amsmath is a lot better.

  • Thanks for the tips =) I use eqnarry only for getting the same spacing before and after all the equality (inequality) signs through the commands &=&. I guess that is not possible with align environment.. – Dion Feb 21 '15 at 22:06

    @Dion that's the point! the spacing used by eqnarray is wrong and is based on the column spacing in array rather than the space that an infix = should have. using align and x&=y then = gets exactly the space it would have in x=y – David Carlisle Feb 21 '15 at 22:18
