A generalization of Hartog's extension of line bundles

Complex Variables 2026-01-15 v1

Abstract

In this article, we prove that if XX is a complex manifold of dimension n4n\geq 4 such that there exists a qq-convex with corners function fFq(X)f\in F_{q}(X), then every holomorphic line bundle over {f>c}\{f>c\} extends uniquely to XX if 1qn31\leq q\leq n-3. This generalizes a well-known result obtained in \cite{ref5} for qq-complete with corners complex manifolds with a corresponding exhaustion function fFq(X)f \in F_{q}(X), when n3qn \geq 3q.
