Moišezon spaces and positive coherent sheaves

In recent papers of Grauert and Riemenschneider, attempts have been made to generalize Kodaira’s embedding theorem to a characterization of Moišezon spaces. In this paper, we define a torsion-free coherent analytic sheaf of generic fiber dimension one as positive if its monoidal transform is positive. We prove: a normal irreducible compact complex space is Moišezon if and only if it carries a positive coherent sheaf of generic fiber dimension one.
