We prove that every continuous, irreducible, odd two-dimensional 2-adic representation of $G_{\mathbb Q}$, unramified outside finitely many primes and de Rham at 2 with distinct Hodge–Tate weights, is modular up to Tate twist. This resolves the odd, regular two-dimensional Fontaine–Mazur conjecture over ℚ at 2, including all residual representations.

It is very clean, which is useful for applications. That said, upon closer inspection this paper may turn out to have some really clever new trick, but I can’t see what that is on a superficial reading. I would actually say I’m surprised that this is a problem OpenAI would have tried to solve,…
