The homalg project -- Algorithmic Homological Algebra

The package homalg is the first and foundational part of the homalg project.

This package provides the matrices used in the homalg project.

The package Modules is a homalg based package for the Abelian category of finitely presented modules over computable rings.

A window to the outer world.

This package provides small dictionaries for homalg to speak (as much as needed of) the languages of Singular, Macaulay2, MAGMA, Sage, and Maple, ...

Communicate with an external system via its shell using I/O streams.

A guide to create a ring for homalg in a supported computer algebra system.
