Foliations on Complex Projective Surfaces
In this text we shall review the classification of foliations on complex projective surfaces according to their Kodaira dimension, following McQuillan’s seminal paper [MQ1] with some complements and variations given by [Br1] and [Br2]. Most of the proofs will be only sketched, and the text should be considered as guidelines to the above works (and related ones), with no exhaustivity nor selfcon...
متن کاملTransversely Projective Structures on a Transversely Holomorphic Foliation
The space of transversely projective structures on a transversely holomorphic foliation is described. Some applications are given.
متن کاملTransversely Projective Structures on a Transversely Holomorphic Foliation, Ii
Given a transversely projective foliation F on a C∞ manifold M and a nonnegative integer k, a transversal differential operator DF (2k + 1) of order 2k + 1 from N⊗k to N⊗(−k−1) is constructed, where N denotes the normal bundle for the foliation. There is a natural homomorphism from the space of all infinitesimal deformations of the transversely projective foliation F to the first cohomology of ...
متن کاملGeneralized Transversely Projective Structure on a Transversely Holomorphic Foliation
The results of Biswas (2000) are extended to the situation of transversely projective foliations. In particular, it is shown that a transversely holomorphic foliation defined using everywhere locally nondegenerate maps to a projective space CPn, and whose transition functions are given by automorphisms of the projective space, has a canonical transversely projective structure. Such a foliation ...
متن کاملOperator Algebra of Transversely Affine Foliations
We establish a geometric condition that determines when a type III von Neumann algebra arises from a foliation whose holonomy becomes affine with respect to a suitable transverse coordinate system. Under such an assumption the Godbillon-Vey class of the foliation becomes trivial in contrast to the case considered in Connes’s famous theorem.
