  - The Heat Kernel Signature (HKS) is a scalar quantity which is derived from the
    heat kernel of a given shape. Due to its robustness, isometry invariance, and
    multiscale nature, it has been successfully applied in many geometric applications.
    From a more general point of view, the HKS can be considered as a descriptor of
    the metric of a Riemannian manifold. Given a symmetric positive definite tensor
    field we may interpret it as the metric of some Riemannian manifold and thereby
    apply the HKS to visualize and analyze the given tensor data. In this paper, we
    propose a generalization of this approach that enables the treatment of indefinite
    tensor fields, like the stress tensor, by interpreting them as a generator of
    a positive definite tensor field. To investigate the usefulness of this approach
    we consider the stress tensor from the two-point-load model example and from a
    mechanical work piece.@eng
