Euler and Pontrjagin Currents of a Section of a Compactified Real Bundle

چکیده
The canonical family of Thom forms s for 0 < s < 1 constructed by Harvey and Lawson on an oriented real vector bundle V ! X with metric connection D V is shown to have a smooth current extension to the bundle of real projective spaces, P(R V) ! X, which compactiies V in the bre directions. The current limit as r ! 1 and s ! 0 of the smooth transgression formula r ? s = r;s is the current equation

متن کاملDivisors and Euler Sparks of Atomic Sections
The purpose of this paper is twofold. The rst purpose is to give a simple treatment of the basic theory of atomic sections and their zero currents or divisors. This theory (see HS,HL1]) places the classical theory of characteristic classes on a new and more general analytic footing based on de Rham currents and geometric measure theory. The second purpose is to discuss an instance of the Cheege...
متن کاملExamples of integrable sub-Riemannian geodesic flows
We exhibit examples of sub-Riemannian metrics with integrable geodesic flows and positive topological entropy. Introduction Consider a distribution on a manifold M, i.e. subbundle of the tangent bundle Π ⊂ TM . Non-holonomic Riemannian metric is a Riemannian metric g ∈ SΠ on this bundle. We call the pair (Π, g) sub-Riemannian structure. A curve γ : [0, 1] → M is called horizontal if γ̇ is a sect...
متن کاملStiefel - Whitney Currents
A canonically defined mod 2 linear dependency current is associated to each collection v of sections, Vl, . . . , Vm, of a real rank n vector bundle. This current is supported on the linear dependency set of v. It is defined whenever the collection v satisfies a weak measure theoretic condition called "atomicity." Essentially any reasonable collection of sections satisfies this condition, vastl...

The /»/'-component of a (An l)-dimensional homotopy sphere 2 e 64„ | = hP4n © (Coker7)4„_ , bounding a spin manifold M is shown to be computable in terms of the signature and the decomposable Pontrjagin numbers of M. Let Bm_i be the group of /»-cobordism classes of (m l)-dimensional homotopy spheres and let bPm C 8m_1 be the subgroup of those homotopy spheres bounding parallelizable w-manifolds...
