From your comments I can see that you mean the marks in the page header but not the chapter headings.
The fancyhdr
package is very popular for customizing page headers and footers. Here's a minimal way to change your header like desired, if everything is default:
\usepackage{fancyhdr}
\pagestyle{fancy}
\renewcommand*{\chaptermark}[1]{\markboth{\MakeUppercase{#1}}{}}}
See also the fancyhdr
documentation.
Here's the solution for the chapter heading, in case you like to do it similar to the page header, for consistency:
You could use the titlesec
package, for example write in your preamble:
\usepackage{titlesec}
\titleformat{\chapter}
{\normalfont\huge\bfseries}{\thechapter}{1em}{}
This way by \chapter{Introduction}
you would get:
1 Introduction
Have a look at the documentation to titlesec
.
I guess you wish to keep the numbering, otherwise you could simply write \chapter*{Introduction}
. Further I assume you don't wish to write everything in capital letters - or do you?
I prefer scrreprt
instead of report
. This class is similar to report but provides many further features. It's default chapter headings style matches the one desired by you.
\documentclass[...]{report}
into\documentclass[...]{scrreprt}
you would notice the headings will change like desired, also without the (in my opinion ugly) upper case. Some other defaults change, but may easily be adjusted.scrreprt
belongs to the KOMA-Script classes which can be used similar to standard classes but offer many more features. – Stefan Kottwitz♦ Feb 28 '11 at 16:27
