On Embedding Manifolds Which Are Bundles over Spheres1
These results were discovered in an attempt to embed real projective spaces. The well-known Hopf fiberings of Pu and Pi give the following representations of these spaces: Pi is a fiber space over S4 with P% as fiber, and Pu is a fiber space over S8 with P7 as fiber. Since any embedding of Pz in R6 has a trivial normal bundle [ó], Theorem 1.2 applies for Pi. Theorem 1.1 applies for Pu and, henc...
متن کاملThe Index of Operators on Foliated Bundles
We compute the equivariant cohomology Chern character of the index of elliptic operators along the leaves of the foliation of a flat bundle. The proof is based on the study of certain algebras of pseudodifferential operators and uses techniques for analizing noncommutative algebras similar to those developed in Algebraic Topology, but in the framework of cyclic cohomology and noncommutative geo...
متن کاملCut-and-paste on Foliated Bundles
We discuss the behaviour of the signature index class of closed foliated bundles under the operation of cutting and pasting. Along the way we establish several index theoretic results: we define Atiyah-Patodi-Singer (≡ APS) index classes for Dirac-type operators on foliated bundles with boundary; we prove a relative index theorem for the difference of two APS-index classes associated to differe...
متن کاملSOME EXAMPLES OF SPHERE BUNDLES OVER SPHERES WHICH ARE LOOP SPACES mod/? BY JOHN EWING
In this note we give sufficient conditions that certain sphere bundles over spheres, denoted Bn(p), are of the homotopy type of loop spaces mod/? for p an odd prime. The method is to construct a classifying space for the /?-profinite completion of Bn(p) by collapsing an Eilenberg-Mac Lane space by the action of a certain finite group. We say that a space X has some property mod/? if the localiz...
متن کاملIndex, Eta and Rho Invariants on Foliated Bundles
We study primary and secondary invariants of leafwise Dirac operators on foliated bundles. Given such an operator, we begin by considering the associated regular self-adjoint operator Dm on the maximal Connes-Skandalis Hilbert module and explain how the functional calculus of Dm encodes both the leafwise calculus and the monodromy calculus in the corresponding von Neumann algebras. When the fol...
