### MAGMA package *ArtinAlgebras*

#### Summary

This package contains functions for handling commutative algebras over fields
(e.g. matrix algebras), such as the computation of the decomposition of such
an algebra into a direct product of its localisations, and the computation of
an isomorphic affine algebra with few relations. Functions testing certain
properties (e.g. the Gorenstein property) are included.

The package is needed for the Magma packages
*Weight1*,
*HeckeAlgebra* and
*pAdicAlgebras*.

Formerly, most functions of this package were included in old versions
of *Weight1* and *HeckeAlgebra*.

#### Download

Here is the complete code, as well as the documentation and an example
as a tar.gz-file.

Here is the manual. It contains a note on
the installation, a long example and precise descriptions of the functions included
in the package.
