The main error occurs on page 306 where it is implicitly assumed that the coefficients of the two operators A*A and AA* (associated to the signature operator A) are polynomial functions in the gij, their derivatives and (det g)-l . As we shall show later this is not quite t r u e t h e coefficients also involve d ] f ~ and the inverses of the principal minors of the matrix gu" Thus the form m in (5.1) is not a regular invariant of the metric in the sense of w 2, and so the Gilkey Theorem as… Expand
The homology of algebras of pseudo-differential symbols and the noncommutative residue
We will perform the calculation by two completely different methods, each of which has some advantages. In the first, we filter the algebra in question as in [2], and use a homogeneity argument toExpand
On the existence of small-time heat expansions for operators with irregular singularities in the coefficients
The asymptotic coefficients in the expansion of Tr e−tH as t → 0+, for H a positive elliptic differential operator of even order, with smooth coefficients, on a compact manifold, are spectralExpand
The decomposition of global conformal invariants II: The Fefferman-Graham ambient metric and the nature of the decomposition
This is the second in a series of papers where we prove a conjecture of Deser and Schwimmer regarding the algebraic structure of ``global conformal invariants''; these are defined to be conformallyExpand
The signature theorem for V-manifolds
Here L(g, M) is the equivariant L-class defined by Atiyah_Singer[4]. By choosing suitable metrics and connections, we can express L(g, M) in differential forms. These characteristic forms are definedExpand
The cohomology of the vector fields on a manifold
‘Continuous’ refers to the usual c topology on Vect(M). (Actually Gelfand and Fuchs considered the cohomology with real coefficients, but we have found it convenient to change from R to C.) In thisExpand
The local index theorem without smoothness
1. Introd llction. The local index theorem has attracted much interest of analysts, geometers, and physicists over the last two decades, rendering its proof more and more perspicuous. All this workExpand
The Heat Kernel
On a closed Riemannian manifold, there are three closely related objects we can study: (i) Topological invariants such as the Euler characteristic and the signature; (ii) Indexes of differentialExpand
Index-free heat kernel coefficients
Using index-free notation, we present the diagonal values of the first five heat kernel coefficients associated with a general Laplace-type operator on a compact Riemannian space without boundary.Expand
Closed geodesics and the y-invariant
In [3], Atiyah, Patodi and Singer introduced an invariant of a Riemannian manifold of dimension 4n 1. This invariant, which they called the p-invariant, is determined by the spectrum of a certainExpand
Supersymmetry, Path Integration, and the Atiyah-Singer Index Theorem
A new supersymmetric proof of the Atiyah-Singer index theorem is presented. The Peierls bracket quantization scheme is used to quantize the supersymmetric classical system corresponding to the indexExpand


The periodicity theorem for the classical groups and some of its applications
In these lectures I hope to trace the development of a subject which has grown up during the past ten years or so and which is now generally known as K-theory. As my starting point I have chosen theExpand

Some Properties of the Eigenfunctions of The Laplace-Operator on Riemannian Manifolds
