Abstract

A vector bundle EE over a projective variety MM is called finite if it satisfies a nontrivial polynomial equation with nonnegative integral coefficients. Introducing finite bundles, Nori proved that EE is finite if and only if the pullback of EE to some finite \'etale covering of MM is trivializable \cite{No1}. The definition of finite bundles extends naturally to holomorphic vector bundles over compact complex manifolds. We prove that a holomorphic vector bundle over a compact complex manifold MM is finite if and only if the pullback of EE to some finite \'etale covering of MM is holomorphically trivializable. Therefore, EE is finite if and only if it admits a flat holomorphic connection with finite monodromy.
