Differential operators and flat connections on a Riemann surface (Q1415245)

Summary: We consider filtered holomorphic vector bundles on a compact Riemann surface \(X\) equipped with a holomorphic connection satisfying a certain transversality condition with respect to the filtration. If \(Q\) is a stable vector bundle of rank \(r\) and degree (1-genus\((X))nr\) then any holomorphic connection on the jet bundle \(J^n(Q)\) satisfies this transversality condition for the natural filtration of \(J^n(Q)\) defined by projections to lower-order jets. The vector bundle \(J^n(Q)\) admits holomorphic connection. The main result is the construction of a bijective correspondence between the space of all equivalence classes of holomorphic vector bundles on \(X\) with a filtration of length \(n\) together with a holomorphic connection satisfying the transversality condition and the space of all isomorphism classes of holomorphic differential operators of order \(n\) whose symbol is the identity map.
