Abstract: 

Let $Y$ be a compact complex manifold embedded in a complex manifold with unitary flat normal bundle.
As a higher-codimensional generalization of Ueda's theory, we investigate the analytic structure of a neighborhood of $Y$.
As an application, we give a criterion for the existence of a smooth Hermitian metric with semi-positive curvature on a nef line bundle.
