    Let \(L\) be a holomorphic line bundle on a projective variety \(X\). Let \(\Omega^p_X\otimes L^{-1}\) denote the sheaf of holomorphic \(p\)-forms with values in \(L^{-1}\) and let \(\kappa(L)\) denote the Kodaira-Iitaka-dimension of \(L\). Then the theorem of Bogomolov says \[ H^0(X,\Omega^p_X\otimes L^{-1})=0 \text{ for } p<\kappa(L). \] The author generalizes the theorem in two respects: \(X\) is a compact Kähler- or Fujiki-manifold and \(\kappa(L)\) is replaced by the effectivity-dimension \(e(L)\) or the numerical dimension \(\nu (L)\) respectively. In this connection \(L\) is a pseudo-effective or a numerical effective line-bundle. The author shows \(\kappa(L)\leq e(L)\leq\nu(L)\) and gives examples for strict inequalities.
