analytic torsion


What is called analytic torsion or Ray-Singer torsion is an invariant of Riemannian manifolds which is an analytic analogue of the invariant of topological manifolds called Reidemeister torsion. It has been proved by Cheeger that the two agree for the compact Riemannian manifolds.
