Latex Beamer Layout Problem

[Richard Pichler]

Hi,

I am preparing a Beamer slide with two simple equations. I wanna include
this in a block as shown below.

\begin{block}{Equation}
\begin{align*}
r &= a + b \\
s &= c + d
\end{align*}
\end{block}

It looks alright, the only problem is that it wastes so much space above
and below the equations. I tried vspace{-2cm} but it did not have any
effect. Any other idea how I could reduce the empty area above and below
the equations. Might it be possible that the block size is fixed and
thats the problem why it takes so much space?

Many thanks for your help

You can set \abovedisplayskip to a negative value, and \belowdisplayskip
to 0

\abovedisplayskip=-2ex
\belowdisplayskip=0pt

This will give you the same spacing relative to the block title as you
would get in e.g. an itemized list.
