Would any people be able to talk to me about the similarities between "simplification" of mathematical expressions, and type-theoretic proofs?
Like, a common task in computer algebra is to automatically rewrite expressions to a "simpler" form. Ideally, you'd have a proof that the simplified expression is equivalent to the original. Could this sort of thing fall out of Lean naturally?

It's the second and last day of the Lean for the Curious Mathematician colloquium in Düsseldorf already! Kaiyu Yang is explaining Theorem Proving via Machine Learning to us on a mathematician(and compiler engineer)-friendly level

The free online textbook "#FunctionalProgramming in #Lean" was completed a couple months ago. Written by David Thrane Christiansen, who also wrote The Little Typer (an excellent introduction to #dependenttypes). I'm working through it now! #leanprover https://leanprover.github.io/functional_programming_in_lean/title.html
