<B><em>xTerior</em></B>: Exterior calculus in Mathematica

<br><br></p>
<h1 id="introduction">Introduction</h1>
<p>
<em>xTerior</em> is a package for exterior calculus running under Mathematica.
Some of its most notable points are:
<ul>
<li> Efficient representation and handling of tensor valued differential forms.
<li>Implementation of the exterior derivative, the exterior covariant derivative, the co-differential and other
standard derivations used in exterior calculus such as the inner contraction and the Lie derivative applied to
differential forms.
<li>Possibility of computing variational derivatives of top rank forms.
<li> Full integration of coordinate charts with the aid of the <em>xAct</em> package <em>xCoba</em>.
Implementation of the standard Cartan structure equations in generic co-bases and explicit
coordinate representations.
</ul>
</p>
<p>
See <a href="xTerior.History">xTerior.History</a>
</p>
<h1 id="download">Download and installation</h1>
<p>Current version: 0.9.0 (as of 23 August 2015). It is recommended to
<a href="../download.html">download the main <em>xAct</em> bundle</a>, but
you can also download the different files separately:</p>
<ul>
<li><a href="./xTerior.nb">xTerior.nb</a>: source file.
<li><a href="./xTerior.m">xTerior.m</a>: package file. This file is
automatically generated by Mathematica when xTerior.nb is saved.
This is the only essential file.
<li><a href="../Documentation/English/xTeriorDoc.nb">xTeriorDoc.nb</a>: main documentation file.
<li><a href="../gpl.txt">General Public License</a>.
</ul>
<p>See the file <a href="./xTerior.readme">xTerior.readme</a> and the
<a href="../download/install">Installation notes</a>.</p>
