We formalize the concepts of holomorphic affine and projective structures along the leaves of holomorphic foliations by curves on complex manifolds. We show that many foliations admit such structures, we provide local normal forms for them at singular points of the foliation, and we prove some index formulae in the case where the ambient manifold is compact. As a consequence of these, we establish that a regular foliation of general type on a compact algebraic manifold of even dimension does not admit a foliated projective structure. Finally, we classify foliated affine and projective structures along regular foliations on compact complex surfaces. [ABSTRACT FROM AUTHOR]

We prove that, in all dimensions, germs of nondegenerate holomorphic vector fields on complex manifolds are univalent in the sense of Palais (semicomplete in the sense of Rebelo), this is, that there exist neighborhoods of their singular points where all their solutions are single-valued. This implies that, in stark contrast with the degenerate case, all germs of nondegenerate holomorphic vector fields give local models for complete holomorphic vector fields on complex manifolds (albeit possibly non-Hausdorff ones).
