Stream: Is there code for X?

Topic: C(S, V) complete and separated


Johan Commelin (Apr 14 2022 at 13:36):

If V is a complete/separated uniform space, do we know that the space of continuous maps C(S, V) is also complete/separated?

We need this for LTE.

Yaël Dillies (Apr 14 2022 at 13:50):

docs#continuous_map.complete_space. I can't find the separated_space instance.

Yaël Dillies (Apr 14 2022 at 13:51):

It is also not quite in the generality you ask for.

Johan Commelin (Apr 14 2022 at 13:53):

Ooh, but that one should be good enough for my purposes. I wonder why I missed it

Yaël Dillies (Apr 14 2022 at 13:54):

yael_search always here to serve!

Anatole Dedecker (Apr 14 2022 at 14:08):

Separation is docs#continuous_map.t2_space

Yaël Dillies (Apr 14 2022 at 14:09):

What is the difference between separated_space and t2_space?

Anatole Dedecker (Apr 14 2022 at 14:09):

If anyone is hungry for refactors (looking at you Yaël) I think we want to throw away docs#separated_space

Anatole Dedecker (Apr 14 2022 at 14:11):

The only difference is that one is expressed about uniformities, but really it should just be a lemma saying « the topology associated to this uniformity is T2 iff […] »
