Topic: Oriented Matroids

Jihoon Hyun (Jan 11 2025 at 03:49):

Is anyone working on oriented matroids? I remember there was a repository for this, but I'm not sure if it aligns well with the current implementation of matroid.

Floris van Doorn (Jan 13 2025 at 13:51):

There is #16239

Julian Berman (Jan 13 2025 at 13:53):

(Those are oriented manifolds right? Not matroids?)

Floris van Doorn (Jan 13 2025 at 21:38):

Oops, I didn't read carefully :man_facepalming:

@Jihoon Hyun I think if you're recalling something matroid-related that probably @Peter Nelson was involved and/or at least might know what the state of things are.

Peter Nelson (Jan 13 2025 at 23:04):

Nothing I know of has been done

Jihoon Hyun (Jan 13 2025 at 23:23):

Then, I might start working on this soon.

For a generalization of matroids that encompasses oriented matroids and some more objects, see https://arxiv.org/abs/2402.09612
