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 |
