# How to change “part” to “chapter”

I am using amsart document class.

The structure order in amsart is Part -> Section -> subsection -> subsubsection

My question: how may I modify \part so that latex would show "Chapter" instead of "Part"?

I tried the idea provided below but it does not work in my latex... :(

Please find below an minimum working example and a screen shot

\documentclass[english, reqno, 9pt]{amsart}
\usepackage{geometry}            % See geometry.pdf to learn the layout options. There are lots.
%\geometry{letterpaper}                   % ... or a4paper or a5paper or ...
%\geometry{landscape}                % Activate for for rotated page geometry
%\usepackage[parfill]{parskip}    % Activate to begin paragraphs with an empty line rather than an indent
\usepackage{amssymb,amsmath,amsthm,amsfonts,color}
\usepackage{mathrsfs,dsfont, comment,mathscinet}
\usepackage{graphicx}
\usepackage{epstopdf}
\usepackage{mathtools}
\usepackage{babel}
\usepackage{enumerate,esint}
\usepackage{natbib}

\usepackage{indentfirst}
\usepackage{bm}
\usepackage{picinpar}
\usepackage{lipsum}

\usepackage[toc,page]{appendix}

\usepackage{etoolbox}
\usepackage{authblk}

\usepackage{caption}
\usepackage{subcaption}

%-----------------------------------------------------------------------------------

\renewcommand{\partname}{Chapter}
\newcommand{\chapter}{\part}

%----------------------------------------------------------------------------------------------

%----------------------------Special for this paper ------------------------------

\title{test}

\begin{document}

\maketitle

\thispagestyle{empty}%this command remove the page number at the title page

\tableofcontents

\chapter{Introduction}

\end{document}

• i'm not sure why you can't use amsbook which comes with \chapter already defined. of course, the amsbook \chapter behaves like a normal book, and starts a new page. i guess you just want everything to continue on without page breaks. – barbara beeton Apr 21 '17 at 0:49

Adjust \partname and make yourself a macro called \chapter so that things make sense conTeXtually (...see what I did there...?):

\documentclass{amsart}

\renewcommand{\partname}{Chapter}
\newcommand{\chapter}{\part}

\begin{document}

\tableofcontents

\chapter{A chapter}
\section{A section}
\subsection{A subsection}
\subsubsection{A subsubsection}

\end{document}


If you're loading babel, then you can use

\newcommand{\chapter}{\part}
\AtBeginDocument{\renewcommand{\partname}{Chapter}}


or

\addto\captionsenglish{\renewcommand{\partname}{Chapter}}


to update \partname.

• I don't know why but it does not work in my case. I provide an minimum working example above. Could you have a look? – JumpJump Apr 21 '17 at 0:23
• @JumpJump: Oh, I see, now you have a huge "minimal" example that loads a bunch of packages... including babel - the culprit. I'll update my answer. – Werner Apr 21 '17 at 0:28
• and yea, my thesis does contains a lot packages... – JumpJump Apr 21 '17 at 0:32
