Mike Shulman just wrote a very nice blog post on what is a formal proof. I much agree with what he says, but I would like to offer my own perspective. I started writing it as a comment to Mike’s post and then realized that it is too long, and that I would like to have it recorded independently as well. Please read Mike’s blog post first.
I am about to give an invited talk at the Workshop on Categorical Logic and Univalent Foundations 2016 in Leeds, UK. It’s a charming workshop that I am enjoing a great deal. Here are the slides of my talk, with speaker notes, as well as the Andromeda examples that I am planning to cover.
