OK, so now item 24 on this list of 100 theorems
cs.ru.nl/~freek/100/
has an *unconditional* formal proof:

I'm teaching algebraic geometry this term. Today is lecture one and I'm going to talk about why the union of two algebraic sets is an algebraic set. I'm formalising the proof in #Leanprover ! My Lean repository is hosted on github at github.com/ImperialColleg… @ImperialMaths

In my alg geom course I prove V(I(V(S)))=V(S), for S a subset of k[X_1,X_2,...,X_n] and V and I the usual functions in the theory of affine alg varieties. I abstracted it and turned it into a new Lean maths challenge tinyurl.com/LeanMathsChall… #leanprover

I've finished updating Lean for Hackers for tonight: agentultra.github.io/lean-for-hacke…
Follow along and you'll learn how to setup Lean and dive right into "Hello, world!" and "Hello, ${name}". This is a guide for hackers so I skip the theory and get straight to it.

Cambridge maths PhD student Bhavik Mehta has formalised around 1/3 of the Part III (MSc) combinatorics course b-mehta.co.uk/iii/mich/combi… in #leanprover . Thorough write-up at b-mehta.github.io/combinatorics/ . Finite sets are tricky, but this is evidence that the API is now there in Lean.

Asked by @boarders__ : if you could take a sabbatical just to formalize (say in #leanprover) the basics of any field of math, which would it be and why?
