For example, I have the following ideal
$I=(1+xy, x+y)$
in $\mathbb{Z}_{2}\left[x,y\right]$ which is a polynomial ring over the field $\mathbb{Z}_2$. How do I calculate the codimension for this simple example? I would like to generalize to free submodules if possiblearpitFri, 25 Jan 2019 07:16:59 +0100https://ask.sagemath.org/question/45174/
