Abstract
We deal with the Levi problem (Hartogs’ inverse problem) for ramified Riemann domains by introducing a positive scalar function \(\rho (a, X)\) for a complex manifold X with a global frame of the holomorphic cotangent bundle by closed Abelian differentials, which is an analogue of Hartogs’ radius. We obtain some geometric conditions in terms of \(\rho (a, X)\) which imply the validity of the Levi problem for finitely sheeted ramified Riemann domains over \({\mathbf {C}}^n\). On the course, we give a new proof of the Behnke–Stein Theorem.
