# Eliminate Vertical Space in 

Im having problems with the vertical space that the  command creates. For example:

\begin{multicols}{2}
\begin{enumerate}
\item  $\sum\limits_{k=1}^{\infty}\frac{k^2e^{-2k}}{k^2+1}$
\item $$\sum\limits_{k=1}^{\infty}\frac{\left|\sin{k^4}\right|}{\sqrt{k^4+1}}$$
\end{enumerate}
\end{multicols}


This creates a vertical space between the \item and the object in the  command. I just want to eliminate this effect. One possible solution is to use the fast math mode: $object$. But, this doesn't satisfy me.

First of all you should not use $$...$$ in LaTeX but $...$. Then: you are asking for display-math which is centered. This causes the vertical space. You need inline math, i.e. use $...$ or $$...$$ instead. You can add \displaystyle at the beginning to get the same style used as before:
\item $\displaystyle\sum\limits_{k=1}^{\infty}\frac{\left|\sin{k^4}\right|}{\sqrt{k^4+1}}$

Hello, your solution was exactly was I was looking for. Thank you very much! Now that you mentioned it, Im a little curious about why I should not use $$...$$ command...! – user4836 Apr 17 '11 at 20:51

For the $$ versus  see the question Why is $…$ preferable to$$?. – Martin Scharrer Apr 17 '11 at 21:00
