Thanks for sharing your expertise. Would you be open to sharing your background? Obviously it's not required, but it would help contextualize what you're saying for the interested non-mathematician; otherwise we're kinda stuck with 'some guy on the Internet said ...' syndrome. :)

Sure, I just created an account a couple of days ago, and my favourite username was already taken :oops:

Hi! Imagine for a moment that your next project required you to develop a lot of functional analysis and PDE theory in Lean. Would you be tempted to build that on top of what you've done (or will have done) with condensed sets?

[deadbeef57]

Right now, I think I would go for that classical approach, simply because there is more supporting material for that in the library, and there are more people who understand that approach and can help contributing. (I'm talking specifically about functional analysis and PDEs here.)

On the other hand, it should be a lot of fun to see if we can formalize the new proof by Clausen--Scholze of Serre duality. Using their machinery, the proof should simplify a lot. But this requires building complex analytic manifolds on top of condensed mathematics. So we would first need to set up those foundations.

Thank you! And welcome! Make yourself at home.
