Talk:Ray is Convex

Do we go for "Ray" terminology of "upper / lower closure" language? Coming as I am from the axioms out, I prefer the language of "closures", although am prepared to acknowledge that indeed, the closures are specifically one-dimensional instances of rays.

But all that will need to be rationalised and explained. Putting this in here to remind myself to do it when I'm not on a random fly-by. --prime mover (talk) 23:12, 24 February 2023 (UTC)
