Holomorphic Lie algebroid connections over rationally connected varieties

Algebraic Geometry 2026-05-28 v1

Abstract

Take a holomorphic Lie algebroid (V,ϕ)(V,\phi) over a rationally connected smooth complex projective variety XX. We show that, under certain conditions, a vector bundle EE over XX admits a (V,ϕ)(V,\phi)-connection if and only if EE is trivial. Moreover, we prove that under the same conditions, any (V,ϕ)(V,\phi)-connection over XX is flat.
