Good morning,


I'm just curious about the following. With a compact Kahler manifold, we can associate an Albanese torus. This helps us a lot study the manifold. 


**My question:** *Are there other holomorphic objects associated with a compact complex manifold?* I'm interested in the objects whose shape is well understood. E.g, an Albanese torus is just a torus, and we know its cohomology, its kahler form etc.


Any help is appreciated. Thanks in advance,

Holomorphic objects associated with a compact complex manifold?
Besides the intermediate Jacobians for Kaehler manifolds, any compact complex manifold has a rational morphism to an algebraic variety, called the algebraic reduction, so that the morphism is an isomorphism of the fields of rational functions: K. Ueno, Classiﬁcation theory of algebraic varieties and compact complex spaces. Notes written in collaboration with P. Cherenack. Lecture Notes in Mathematics, Vol. 439. Springer-Verlag, Berlin-New York, 1975. Careful: the algebraic reduction is only defined up to birational isomorphism. If the canonical bundle is effective, then one can also define the canonical map, from the compact complex manifold to projective space. There are also moduli spaces of coherent sheaves. None of these really have their shape understood though. The biholomorphism group of a compact complex manifold is a finite dimensional complex Lie group, so its shape is essentially understood.
