OIGroebnerBases -- OI-modules over Noetherian polynomial OI-algebras

Description

OIGroebnerBases is a package for Gröbner bases, syzygies and free resolutions for submodules of free OI-modules over Noetherian polynomial OI-algebras. For an introduction to the theory of OI-modules, see [3].

Given a Noetherian polynomial OI-algebra $\mathbf{P} := (\mathbf{X}^{\text{OI},1})^{\otimes c}$ for some integer $c > 0$, one can consider free OI-modules $\mathbf{F} := \bigoplus_{i=1}^s\mathbf{F}^{\text{OI}, d_i}$ over $\mathbf{P}$ for integers $d_i\geq 0$.

Gröbner bases for submodules of $\mathbf{F}$ were introduced in [3]. Free resolutions and homological aspects of submodules have been studied in [2,3]. Using the methods of [1], Gröbner bases, syzygy modules, and free resolutions for submodules can be computed with oiGB, oiSyz and oiRes respectively.
