J ul 1 99 8 REMOVING METRIC ANOMALIES FROM RAY SINGER TORSION
نویسنده
چکیده
Ray Singer torsion is a numerical invariant associated with a compact manifold equipped with a flat bundle, a Riemannian metric on the manifold and a Hermitian structure on the bundle. In this note we show how one can remove the dependence on the Riemannian metric and the Hermitian structure with the help of a base point and of an Euler structure, and obtain a topological invariant. A numerical invariant for an Euler structure and additional data is also constructed.

Witten Deformation of Ray-singer Analytic Torsion
Let F be a flat vector bundle over a compact Riemannian manifold M and let f : M → R be a self-indexing Morse function. Let g be a smooth Euclidean metric on F , let g t = e g and let ρ(t) be the Ray-Singer analytic torsion of F associated to the metric g t . Assuming that ∇f satisfies the MorseSmale transversality conditions, we provide an asymptotic expansion for log ρ(t) for t → ∞ of the for...

In this paper we define a Poincaré-Reidemeister scalar product on the determinant line of the cohomology of any flat vector bundle over a closed orientable odd-dimensional manifold. It is a combinatorial “torsion-type” invariant which refines the PR-metric introduced in [Fa] and contains an additional sign or phase information. We compute the PR-scalar product in terms of the torsions of Euler ...

Let K denote a closed odd-dimensional smooth manifold and let E be a flat vector bundle over K. In this situation the construction of Ray and Singer [RS] gives a metric on the determinant line of the cohomology detH(M ;E) which is a smooth invariant of the manifold M and the flat bundle E. (Note that if the dimension of K is even then the Ray-Singer metric depends on the choice of a Riemannian ...

Let (X, [ω]) be a compact Kähler manifold with a fixed Kähler class [ω]. Let K ω be the set of all Kähler metrics on X whose Kähler class equals [ω]. In this paper we investigate the critical points of the functional g ∈ K ω → Q(g) = v g T 0 (X, g) 1/2 , where v is a fixed nonzero vector of the determinant line λ(X) associated to H * (X) and T 0 (X, g) is the Ray-Singer analytic torsion. For a ...
