Energy in Topologically Massive Gravity
S. Deser, Bayram Tekin
We define conserved gravitational charges in -cosmologically extended- topologically massive gravity, exhibit them in surface integral form about their de-Sitter or flat vacua and…
Shortcuts to high symmetry solutions in gravitational theories
S. Deser, Bayram Tekin
We apply the Weyl method, as sanctioned by Palais' symmetric criticality theorems, to obtain those -highly symmetric -geometries amenable to explicit solution, in generic gravitati…
Novel Properties of Massive Higher Spin Fields
S. Deser
I outline a series of results obtained in collaboration with A. Waldron on the properties of massive higher (s>1) spin fields in cosmological, constant curvature, backgrounds and t…
A Note on Matter Superenergy Tensors
S. Deser
We consider Bel-Robinson-like higher derivative conserved two-index tensors $H_\mn$ in simple matter models, following a recently suggested Maxwell field version. In flat space, we…
Acausality of Massive Charged Spin 2 Fields
S. Deser, A. Waldron
The recent claim in hep-th/0302225 that, contrary to all previous work, massive charged s=2 fields propagate causally is false.
Energy in Generic Higher Curvature Gravity Theories
S. Deser, Bayram Tekin
We define and compute the energy of higher curvature gravity theories in arbitrary dimensions. Generically, these theories admit constant curvature vacua (even in the absence of an…
