## Stream: condensed mathematics

#### Johan Commelin (Feb 10 2021 at 08:35):

I've made a couple of changes to the repo with the following effect:

If you now compile src/liquid.lean you should get only 2 warnings about sorry: one for thm95 and one for first_target.
The second sorry should be easy to fill in, by reducing it to thm95.

To make this possible, I have moved code that was sorryd to new files that are not in the dependency chain of src/liquid.lean. Of course they should end up in the dependency chain at some point, once they are sorry-free, and used in the proof of thm95.

I have also replace every occurence of sorry in commented code by the word admit, which is functionally equivalent (in tactic mode).
This means that we can now run

rg sorry | wc -l
12


to find that we have 12 lines containing uncommented sorrys (of which 2 are in the README).

Since you are in a cleaning up mood, could you get us rid of the undefined references in the blueprint? They are also generating a lot of noise.

I need to prepare a talk on type theory first...

#### Johan Commelin (Feb 10 2021 at 09:21):

But I think I'll stay in cleaning up mood for a couple of days, now that thm95 is in place.

We need to clean up the mess before we sprint onto the battlefield

These files contain code that has been generalised in order to state thm 9.5. Repo just shrunk with about 10% (-;

I fixed those. But with a "hack". I just put things in a sort of appendix, and we should move them to a better place in the next refactor of the blueprint
