# Suppress Chapter Number and Chapter Title Completely [duplicate]

I am working on the layout of my PhD thesis. For designing purpose, I would like to suppress the chapter number and chapter title completely without disturbing section numbering (Figure below).

Well, I managed to remove the chapter title easily by \chapter{}. Although with \chapter*{} chapter number disappears, it affects the section numbers. Is there any way to achieve this without disturbing section numbering?

Please note that the Table of Content is not important.

my (sample) working code is as below:

\documentclass[11pt,twoside,openright]{report}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{lipsum}
\usepackage{appendix}

\usepackage{titlesec}
\titleformat{\chapter}[display]
{\centering\huge\bfseries}{\LARGE\centering\MakeUppercase\thechapter\thispagestyle{empty}}{1pc}{}
\titlespacing*{\chapter}{0pt}{0pt}{0pt}

\begin{document}

\tableofcontents
\pagenumbering{arabic} \setcounter{page}{1}

%\chapter{Ch one}
\chapter*{}
\vspace{1cm}
\begin{center}
\textbf{{\Large Abstract}}
\end{center}
\lipsum[2-3]

\mbox{}
\vfill

\noindent This chapter is based on:\newline

\noindent Text text text Text text text Text text text Text text text Text text text Text text text Text text text Text text text Text text text Text text text Text text text Text text text Text text text Text text text Text text text Text text text .

\hspace{0pt}
\pagebreak

\section{section 1}
\lipsum[2-5]

\section{section 2}
\lipsum[2-5]

\end{document}


• Or alternatively something like tex.stackexchange.com/questions/124326/… with section instead of chapter. – Marijn May 27 '19 at 15:29
• Why do you want to remove the chapter numbers and titles? Can't you leave out the \chapter commands in that case completely? Or perhaps using the article class instead is even more appropriate – siracusa May 27 '19 at 15:53
• @siracusa: Following on your comment, I solved the question by resetting section numbers in combination with skipping \chapter. Thanks :) – pukumarathe May 29 '19 at 10:49
