# Formatting chapter style in REPORT document class [closed]

I am trying to write my Thesis using LaTeX. I am using the report document class. I have created multiple TeX files (one each for abstract, acknowledgment, and chapters) using 'chapters'. When I use the titlesec package to format the chapter heading it applies to the whole document changing even the table of content, list of figures and list of tables.

I want to keep the default chapter heading style for frontmatter and use a custom chapter style for the mainmatter

Is there a way to apply different chapter style (default/multiple custom styles) to different chapters in the same document? Something similar to pagestyle!

It is certainly possible to redefine chapter later in the document. But imho you shouldn't do it. –  Ulrike Fischer Apr 30 '14 at 15:42
Can you show the code you have for redefining the chapter style? –  egreg Apr 30 '14 at 17:33

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

\clearpage

\fancypagestyle{plain}{%redefining plain pagestyle
