amsartgeometryheader-footertypearea
There is a oneside option in the package typearea. It is well suited for online documents, since the page layout is the same for every page. However, when used with amsart document class, there is no switch of headers on even/odd pages. In two-sided mode there is title on odd pages and author name on even pages. Is it possible to make pages symmetric but with switching headers?
Solutions with geometry are also welcome.
In your headers you have three pieces of information: chapter, section and subsection. Standard LaTeX only has two marks, \leftmark and \rightmark, so this doesn't fit. Fortunately, chapters always start at a new page, so you can put the chapter header in a macro, and then you can use \leftmark for section and \rightmark for subsection.
\newcommand{\chaptertitle}{}
\renewcommand{\chaptermark}[1]{\renewcommand{\chaptertitle}{Chapter \thechapter\ #1}}
\renewcommand{\sectionmark}[1]{\markboth{\thesection\ #1}{}}
\renewcommand{\subsectionmark}[1]{\markright{\thesubsection\ #1}}
\pagestyle{fancy}
\fancyhf{}
\fancyhead[LO]{\chaptertitle}
\fancyhead[LE]{\leftmark}
\fancyhead[RE]{\rightmark}
\fancyfoot[LE,RO]{\thepage}
As Peter Wilson said you could use a twoside document but with the same left and right margins, which can be done with the geometry package. Something like
\usepackage[leftmargin=5cm,rightmargin=5cm]{geometry}
The other way is to use a oneside document and use the \ifodd\value{page} as you have done in your code, but using \leftmark and \rightmark. This is the solution that I am offering you.
\documentclass[oneside]{report}
\usepackage{fancyhdr}
\usepackage{lipsum}
\pagestyle{fancy}
\newcommand\cotitle{Chapter 1 Title}
\newcommand\secco{Chapter 1, Section 1 Title}
\fancyhf{}
\renewcommand\headrulewidth{0pt}
\fancyhead[C]{%
\small\scshape
\ifodd\value{page}
\leftmark
\else
\rightmark
\fi}
\fancyhead[L]{\ifodd\value{page}\else\thepage\fi}
\fancyhead[R]{\ifodd\value{page}\thepage\fi}
\begin{document}
\chapter{Introduction}
\lipsum[1]
\section{The first section}
\lipsum[2-11]
\end{document}

The
amsartclass has its own method for setting the pagination parameters. In one- or twosided mode, the layout is symmetric.
