I wrote a short note about the focusing proof I thought of the other day and put it up on my drafts page. I revised it so that it doesn't actually have anything to do with funny cointuitionistic lax logic anymore; that was a red herring. It's just linear logic where you interpret uparrow as q-tensor-blank and downarrow as q-lolli-blank.

It's an awfully lovely bit of math to my aesthetic sense. Too bad I can't find time to work on it more, or, more to the point, find much more of consequence to say about it. It's not like we didn't know focusing was complete already. I just like compressing the proofs like hell until they make sense to me.

    Not sure this is the simplest possible inverse (or even that it is correct) but it makes for a fun diagram:
