  • We study the heat equation of a Riemannian Manifold (M,g), from which
    we derive the analytic betti-numbers and analytic torsion. While the former is
    a topological invariant,

    the latter need not always be. We introduce variations of the analytic torsion
    and explain their relations to other invariants.
