Abstract:
In complex geometry a classical and useful invariant of a complex manifold is its Kodaira dimension.
Since its introduction by Iitaka in the early 70's, its behavior under deformations was object of
study and it is known that Kodaira dimension is invariant under holomorphic deformations for smooth
projective manifolds, while there are examples of holomorphic deformations of nonprojective manifolds
for which the Kodaira dimension is nonconstant. Recently this concept has been generalized to almost
complex manifolds, we want to present here some of its main features in the nonintegrable case, mainly
with respect to deformations. At the end we conclude with some speculations on the theory of meromorphic
functions on almost complex manifolds.
