Groebner.jl

The package provides Groebner bases computation interface in pure Julia with the performance comparable to Singular. Groebner.jl works over finite fields and the rationals, and supports various monomial orderings.

How to use Groebner.jl?

Our package works with polynomials from AbstractAlgebra.jl, DynamicPolynomials.jl, and Nemo.jl. We will demonstrate the usage on a simple example. Lets first create a ring of polynomials in 3 variables

using AbstractAlgebra
R, (x1, x2, x3) = PolynomialRing(QQ, ["x1", "x2", "x3"]);

Then we can define a simple polynomial system

polys = [
  x1 + x2 + x3,
  x1*x2 + x1*x3 + x2*x3,
  x1*x2*x3 - 1
];

And compute the Groebner basis passing the system to groebner

using Groebner
G = groebner(polys)
3-element Vector{AbstractAlgebra.Generic.MPoly{Rational{BigInt}}}:
 x1 + x2 + x3
 x2^2 + x2*x3 + x3^2
 x3^3 - 1

Performance

We compare the runtime of our implementation against the ones from Singular and Maple computer algebra systems. The table below lists measured runtimes of Groebner basis routine for several standard benchmark systems in seconds

The bases are computed in degrevlex monomial ordering over finite field of characteristic $2^{31}-1$ with all operations single-threaded.

We emphasize that Groebner.jl is a specialized library while Singular is an extensive general purpose computer algebra system.
