# Help regarding heading and page numbers

I want to place the heading in the middle and the page number below in Latex. Please suggest how to do it.

I am using the following coding.

\chapter{$\Lambda$-Modules}\ref{ch:prili}
\markright{~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Chapter
\ref{ch:prili}:~Preliminaries}
\thispagestyle{empty}


The fancyhdr package provides a lot of options for customizing headers and footers, including control over the location of page numbers. Having the page number at the bottom and a centered header text could go like this, for a simple example:

\documentclass{book}

\usepackage{fancyhdr}
\pagestyle{fancy}

\cfoot{\thepage} % Can also use \lfoot or \rfoot

\begin{document}
...


fancyhdr is the easiest way to go. \usepackage{google} for more info. i think you want something like (not tested)

\usepackage{fancyhdr}
