I am going to open a PR to have for_mathlib/SemiNormedGroup_Completion in mathlib. I created the file but I am not the original author (git blame and github history only show me and Johan as authors), and I don't remember who wrote it in the first place. If you want to be mentioned in the authors list let me know.

You shouldn't need to come back to things like completion.induction_on₂. It means that either some lemmas are missing in mathlib or their use is missing in LTE.

Patrick Massot (Oct 18 2021 at 11:52):

I'll try to fix this soonish. Could you please tag the PR as WIP and ping me if I forget to work on it?

Riccardo Brasca (Oct 18 2021 at 11:54):

OK!

Riccardo Brasca (Oct 18 2021 at 11:56):

Indeed this can probably be golfed a lot using the results in analysis.normed.group.hom_completion. Let me see what I can do.

Riccardo Brasca (Oct 18 2021 at 12:58):

It seems that the only missing thing in analysis.normed.group.hom_completion is the extension to the completion of a morphism with complete codomain. I am working on it.

Riccardo Brasca (Oct 18 2021 at 13:51):

It should be ready for review now.

Patrick Massot (Oct 18 2021 at 14:18):

Indeed it looks much better now

Patrick Massot (Oct 18 2021 at 14:27):

I reviewed it.
