Query: Irreducible connections admit generic oper structures   Let G be a connected reductive group and X be a smooth curve over an
algebraically closed field of characteristic zero. We show that every
meromorphic G-connection on X admits a possibly degenerate oper structure; in
particular, every irreducible meromorphic G-connection admits a generic oper
structure.
