[Tex/LaTex] Proper way of vertical spacing before/after environments

spacing

I am trying to typeset my thesis. I have to put predefined vertical space before and after some specific environments like equation and table. Since there are many instances of these environments I do not want to put space manually. I also do not want to define a new environment like

\newenvironment{equ}{\vspace{1cm}\begin{equation}}{\end{equation}\vspace{15mm}}

I think the above approach is ugly. I think I have to redefine the environments but

\renewenvironment{equation}{\vspace{1cm}\begin{equation}}{\end{equation}\vspace{15mm}}

does not work. What is the best way of setting space before and after some specific environments?

UPDATE

I found a solution.

Try

\setlength{\abovedisplayskip}{1cm}
\setlength{\belowdisplayskip}{1cm}

You have to place these inside the document, i.e. after \begin{document} and before \end{document}.

You can set the length abovedisplayskip to 0pt (or any other desired value):

\documentclass{beamer}
\usepackage{amsmath}
\begin{document}

\begin{frame}
\begin{block}{Separation of variables}
\begin{gather*}
 u'''' - (yu')' = \lambda u,\\
u''(0)=u'''(0)=0 \quad \text{(Free),} \qquad u(1)=u''(1)=0 \quad\text{(Clamped)}
\end{gather*}
\end{block}
\begin{block}{Separation of variables}
\setlength\abovedisplayskip{0pt}
\begin{gather*}
 u'''' - (yu')' = \lambda u,\\
u''(0)=u'''(0)=0 \quad \text{(Free),} \qquad u(1)=u''(1)=0 \quad\text{(Clamped)}
\end{gather*}
\end{block}
\end{frame}
\end{document}

Of course, you can use something like

\addtobeamertemplate{block begin}{\setlength\abovedisplayskip{0pt}}

right after \begin{document} to apply the change to all the blocks.

[Tex/LaTex] reduce vspace after section header

Here's a way for switching between sections with tighter spacing and sections with normal spacing, done by redefing the \section command of scrartcl:

\documentclass{scrartcl}
\newcommand{\breaksection}[1]{#1\par\noindent}
\usepackage{letltxmacro}
\LetLtxMacro{\oldsection}{\section}
\makeatletter
\newcommand*{\smallsection}{
  \renewcommand{\section}{\@startsection{section}{1}{\z@}%
    {-3.5ex \@plus -1ex \@minus -.2ex}%
    {0ex}%
    {\ifnum \scr@compatibility>\@nameuse{scr@v@2.96}\relax
      \setlength{\parfillskip}{\z@ plus 1fil}\fi
      \raggedsection\normalfont\sectfont\nobreak\size@section\breaksection}%
  }
}
\makeatother
\newcommand*{\stdsection}{\LetLtxMacro{\section}{\oldsection}}
\begin{document}
\section{One}
text
\smallsection
\section{Two}
text
\stdsection
\section{Three}
text
\end{document}

It copies the original definition from scrartcl but uses 0ex for the new space after the heading, which is 2.3ex \@plus.2ex by default. \breaksection is defined to get a paragraph break after the heading, without it you would get a run-in heading: a positive value causes a skip below, a negative value a run-in heading with that horizontal space.
