Documentation Build Status GitHub Actions

Introduction

The Julia package HomalgProject provides simplified access to the repositories of the GAP packages hosted at the GitHub organization homalg-project, most of which are based on the

These are open source GAP multi-package projects for constructive category theory and homological algebra with applications to module theory of commutative and non-commutative algebras and algebraic geometry.

Installation

To install Julia follow the instructions of the first two steps on the Oscar installation page. Then start Julia and add the package HomalgProject:

$ julia
julia> using Pkg; Pkg.add("HomalgProject")

For more information on the included GAP packages see the documentation.

The correctness of the installation and the availability of the functionality can at any time be tested using

julia> using Pkg; Pkg.test("HomalgProject")

After each update of the Julia package GAP a rebuild is (probably) necessary:

julia> using Pkg; Pkg.build("HomalgProject")

Software dependency

HomalgProject relies on the

computer algebra systems through the Julia packages
GAP Gap.jl
Nemo Nemo = Nemo.jl
Singular Singular.jl

all of which are components of the computer algebra system OSCAR.

Some of the bundled packages use the GAP packages

and the

third party software through the GAP packages
cddlib CddInterface
4ti2 4ti2Interface
Normaliz NormalizInterface
Graphviz Digraphs
