The beginning of section 2 in the paper by Beilinson-Drinfeld directly answers the first question with the additional assumption that the differential operator has nowhere vanishing principal symbol. So representing the vector bundle locally on a coordinate open as $\mathcal{D}_1(U)/ \mathcal{D}_1P(U)$ the differential operators $P(U)$ only glue to a differential operator with non vanishing principal symbol if the bundle has in fact an oper structure. | |

| May 29, 2020 at 17:39 | comment | added | Andy Sanders | I think the answer to your question should be contained, or at least intimated, in these notes of Richard Wentworth: arxiv.org/abs/1402.4203. | |
