Thank you, Kodlu, for noticing this typo.

]]>Well, a point for ETH in the rivalry.

]]>That’s very encouraging. Despite all the criticisms of Lean by Prof Hales, I think I will give it a try.

]]>FLT will take some work! What can “easily” be done now is the beginning of the process, where one starts to formalise statements such as the Langlands-Tunnell theorem, Mazur’s theorem on torsion points, Ribet’s theorem, the Shimura-Taniyama-Weil conjecture, an R=T theorem etc etc and starts to prove theorems saying how all these things are related. Occasionally one will run into things which need a lot of technology, for example Langlands-Tunnell needs all the machinery of the trace formula for (non-compact) GL_2, and Ribet’s theorem needs all the machinery of the reduction of modular curves (and in particular a bunch of algebraic geometry) but certainly proving things like R=T at minimal level (the Taylor-Wiles theorem) looks accessible to me (a lot of the work will be making definitions). The full proof uses so much stuff though.
