Topic: Notation for fields


Sebastien Gouezel (Aug 27 2019 at 15:20):

Currently, a field is often denoted by k, but so are integer numbers or many things. I don't know how to do \mathbb{k}, but I have just learned that \bbK gives 𝕂. Would a pull request replacing all instances of a field k by 𝕂 be welcome?

Johan Commelin (Aug 27 2019 at 15:21):

What about just capital K? That's very common in the literature.

Johan Commelin (Aug 27 2019 at 15:22):

I've seen people use \bbK to denote either \bbR or \bbC, but for general fields, I think K is very common.

Sebastien Gouezel (Aug 27 2019 at 15:22):

The less ambiguity the better, I would say. And we have unicode, so let's use it!

Johan Commelin (Aug 27 2019 at 15:22):

Well, are there many other uses of K?

Sebastien Gouezel (Aug 27 2019 at 15:22):

compact sets?

Johan Commelin (Aug 27 2019 at 15:22):

Ok, sure

Algebraists...

Johan Commelin (Aug 27 2019 at 15:23):

Sorry...

Johan Commelin (Aug 27 2019 at 15:24):

I don't really care... everything is better than \beta

Johan Commelin (Aug 27 2019 at 15:24):

(Yep, \beta, because for some silly reason \alpha was already used as a compact set.)

Done in #1363
