Characteristic Classes of Transversely Homogeneous Foliations
The foliations studied in this paper have transverse geometry modeled on a homogeneous space G/H with transition functions given by the left action of G. It is shown that the characteristic classes for such a foliation are determined by invariants of a certain flat bundle. This is used to prove that when G is semisimple, the characteristic classes are rigid under smooth deformations, extending ...
متن کاملNoncommutative rings and characteristic classes of foliations
The notion of a characteristic fibration is introduced. This fibration consists of a base space M and a set of fibres which are dimension groups associated to a noncommutative ring R. Every dimension group of the fibration is isomorphic to the first Betti group of M with a ‘positive cone’ depending continuously on the fibre. The characteristic fibrations are linked to the codimension–1 regular ...
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.
متن کاملTransversely Hessian foliations and information geometry
A family of probability distributions parametrized by an open domain Λ in Rn defines the Fisher information matrix on this domain which is positive semi-definite. In information geometry the standard assumption has been that the Fisher information matrix is positive definite defining in this way a Riemannian metric on Λ. If we replace the "positive definite" assumption by "0-deformable" conditi...
متن کاملOn some classes of foliations
The goal of the paper is to present in a unitary way some conditions that a foliation be Riemannian, involving general conditions on higher order normal bundles (jets or accelerations). M.S.C. 2010: 53C12, 57R10, 55R10, 55R15, 58A20.
