# Chow lemma for complex spaces

Is there something like the Chow lemma for complex spaces (stating that every compact complex space is birational to a projective variety, or some variant of this, like: every proper morphism of complex spaces is birational to a projective morphism)?

For projective spaces, the transcendence degree of the field of meromorphic functions is equal to the dimension. For arbitrary compact analytic spaces, it can be smaller. So asking for a birational map is too much. –  Jérôme Poineau Oct 23 '13 at 6:31
Just a nitpick: it's probably better to say "projective variety" rather than "projective space"; by convention the latter really means some $\mathbf{P}^n$. –  Artie Prendergast-Smith Oct 23 '13 at 7:47
And every (proper) morphism of projective varieties is in fact projective. –  ulrich Oct 23 '13 at 9:21
@ArtiePrendergast-Smith: Thank you. That was what I meant of course. –  Jérôme Poineau Oct 23 '13 at 9:23
@JérômePoineau: just to clarify, my comment was really meant for the OP, not you! –  Artie Prendergast-Smith Oct 23 '13 at 12:28

As pointed out in the comments, if a complex compact manifold $X$ of dimension $n$ is bimeromorphic to a projective variety, its field of meromorphic functions must have transcendence degree $n$ (the maximum possible) -- one says that $X$ is a Moisezon manifold. Conversely, a deep theorem of Moisezon asserts that any compact Moisezon manifold becomes projective after a finite number of blowing ups with smooth centers.
