Spacing between minitoc and next section

Question

Please, how can I delete space between minitoc and the introduction?

\chapter{chapter 1}
\renewcommand{\baselinestretch}{1}
\minitoc
\label{CHAPTER1}
\thispagestyle{empty}
\section{Introduction}

Answer 1

You can use \vspace to add or delete vertical space before or after \minitoc. For example:

\vspace{-8ex}
\minitoc
\vspace{-2ex}

You can also define this group of commands as new command (\miniminitoc, for instance) in the preample:

\newcommand{\miniminitoc}{
\vspace{-11ex}
\minitoc
\vspace{-5ex}}

And then simply change \minitoc by \miniminitoc in all chapters. This is convenient to maintain a clean code in the body but also for subsequent adjustments (since only is needed to make changes in the preamble to adjust all the indexs)
