# Renaming abstract in amsbook

I am writing my thesis and I am using the class amsbook.

I am using the abstract environment at the beginning of each chapter to make a short summary of the chapter itself. (I imagine this is not so good, right? But I like it. Do you have any suggestions in the case this is not typographically recommended?)

In any case, I was wondering how to rename the environment, so that instead of "Abstract" it appears something like "Summary of the chapter".

I have been trying using the command

\renewcommand{\abstractname}{Summary of the chapter}


but it does not work. The output is always "Abstract."

EDIT: Here is an example of working code.

\documentclass[a4paper, 10pt, twoside, reqno]{amsbook}
\usepackage[english]{babel}
\usepackage{lipsum}
\title{Thesis}
\author{me}

\begin{document}
\maketitle

\chapter{Chapter 1}
\begin{abstract}
Abstract of the first chapter.
\lipsum[1-2]

\end{abstract}

\lipsum[1-2]
\end{document}


which produces (a part from the title page)

• An example of code would be welcome. I get no output from \chapter{Title}\begin{abstract}text\end{abstract} other than the chapter title. Jul 23 '17 at 13:22
• In amsbook the abstract is considered part of the \maketitle (like \author). So basically what you want is an unnumbered section (like \section*}. Jul 23 '17 at 13:28
• @egreg Added miminal working example and picture. Is it possible to change the word "Abstract" into something else? Thanks for the interest. Jul 23 '17 at 14:48

The abstract environment works just by chance.

I suggest to define your own environment, here identical to abstract, but customizable.

\documentclass[a4paper, 10pt, twoside, reqno]{amsbook}
\usepackage[english]{babel}
\usepackage{lipsum}

\makeatletter
\newenvironment{chaptersummary}{%
\normalfont\Small
\list{}{%
\labelwidth\z@
\leftmargin3pc
\rightmargin\leftmargin
\listparindent\normalparindent
\itemindent\z@
\parsep\z@ \@plus\p@
\let\fullwidthdisplay\relax
}%
\item[\hskip\labelsep\scshape\chaptersummaryname.]%
}{%
\endlist
}
\makeatother

\providecommand{\chaptersummaryname}{Summary of the chapter}

\begin{document}

\chapter{Chapter 1}

\begin{chaptersummary}
Abstract of the first chapter.
\lipsum[1-2]
\end{chaptersummary}

\lipsum[1-2]

\end{document}


• This is exactly what I was looking for. Thanks a lot for your help. Jul 23 '17 at 15:46

You can define your own summary environment, and format it with the quoting package/environment:

\documentclass{amsbook}
\usepackage{lipsum}
\usepackage{quoting}
\newenvironment{summary}{%
\quotingsetup{font=small, leftmargin=2em, rightmargin=0pt, vskip=3ex } \centering{\bfseries Chapter summary}\vspace{-2ex}\quoting}{\endquoting}

\begin{document}

\chapter{A Test Chapter}
\begin{summary}
\lipsum[1]
\end{summary}

\lipsum
\end{document}


%Simple just use this!

\begin{center}
\textbf{Summary}\\
\vspace{0.2cm}
This report will go over the functions blocks used in the Delta V Control Studio along with their mneumonics and short descriptions
\end{center}
