New Proof of the Cobordism Invariance of the Index
نویسنده
چکیده
We give a simple proof of the cobordism invariance of the index of an elliptic operator. The proof is based on a study of a Witten-type deformation of an extension of the operator to a complete Riemannian manifold. One of the advantages of our approach is that it allows to treat directly general elliptic operator which are not of Dirac type.

On Carvalho’s K-theoretic formulation of the cobordism invariance of the index
We give a direct proof of the fact that the index of an elliptic operator on the boundary of a compact manifold vanishes when the principal symbol comes from the restriction of a K-theory class from the interior. The proof uses noncommutative residues inside the calculus of cusp pseudodifferential operators of Melrose. Introduction A classical result of Thom states that the topological signatur...
متن کاملCobordism Invariance of the Index
We give a proof of the cobordism invariance of the index of elliptic pseudodifferential operators on σ-compact manifolds, where, in the non-compact case, the operators are assumed to be multiplication outside a compact set. We show that, if the principal symbol class of such an elliptic operator on the boundary of a manifold X has a suitable extension to K1(TX), then its index is zero. This con...
متن کاملOn the Cobordism Invariance of the Index of Dirac Operators
We describe a “tunneling” proof of the cobordism invariance of the index of Dirac operators. The goal of this note is to present a very short proof of the cobordism invariance of the index. More precisely, if D̂ is a Dirac operator on an odd dimensional manifold M̂ with boundary ∂M̂ = M then we show that the index of its restriction D to M is zero. The novelty of this proof consists in the fact th...
متن کاملCobordism invariance of the family index
We give a K-theory proof of the invariance under cobordism of the family index. We consider elliptic pseudodifferential families on a continuous fibre bundle with smooth fibres M →֒ M → B, and define a notion of cobordant families using K-groups on fibrations with boundary. We show that the index of two such families is the same using properties of the push-forward map in K-theory to reduce it t...
متن کاملCusp geometry and the cobordism invariance of the index
The cobordism invariance of the index on closed manifolds is reproved using the calculus Ψc of cusp pseudodifferential operators on a manifold with boundary. More generally, on a compact manifold with corners, the existence of a symmetric cusp differential operator of order 1 and of Dirac type near the boundary implies that the sum of the indices of the induced operators on the hyperfaces is null.
