Canonical and gravitational stress-energy tensors
It is dealt with the question, under which circumstances the canonical Noether stress-energy tensor is equivalent to the gravitational (Hilbert) tensor for general matter fields under the influence of gravity. In the framework of general relativity, the full equivalence is established for matter fields that do not couple to the metric derivatives. Spinor fields are included into our analysis by...
متن کاملGauge Invariant Effective Stress-energy Tensors for Gravitational Waves
It is shown that if a generalized definition of gauge invariance is used, gauge invariant effective stress-energy tensors for gravitational waves and other gravitational perturbations can be defined in a much larger variety of circumstances than has previously been possible. In particular it is no longer necessary to average the stress-energy tensor over a region of spacetime which is larger in...
متن کاملStress-Energy Tensors for Higher Dimensional Gravity
We calculate, in the context of higher dimensional gravity, the stress-energy tensor and Weyl anomaly associated with anti-de Sitter and anti-de Sitter black hole solutions. The boundary counter-term method is used to regularize the action and the resulting stress-energy tensor yields both the correct black hole energies as well as a vacuum energy contribution which is interpreted as a Casimir ...
متن کاملMatchings and Canonical Forms for Symmetric Tensors
Let V be a q-dimensional vector space. Fix a set B of q(q − 1) monomials in S(V ) of the form x where ik > 0 for all k. The generic element of S(V ) is conjugate under a suitable linear transformation to an element with support off of B. We prove this by showing the existence of a perfect matching with a unique weight in a certain weighted bipartite graph. Such a perfect matching corresponds to...
متن کاملKernels of Canonical Algebraic Curvature Tensors
In this paper, we generalize a result on the possible dimensions of the kernel of a linear combination of a particular type of canonical algebraic curvature tensors. We then introduce a new framework for viewing canonical algebraic curvature tensors, using the wedge product, which allows us to give shorter and more transparent proofs of some basic facts about these tensors.
