Energy in Topologically Massive Gravity
We define conserved gravitational charges in -cosmologically extendedtopologically massive gravity , exhibit them in surface integral form about their de-Sitter or flat vacua and verify their correctness in terms of two basic types of solution. e-mail: deser,[email protected] Address after July 15, Physics Department, Middle East Technical University, 06531 Ankara, Turkey. Recently [1], we def...
متن کاملRenormalizability of Topologically Massive Gravity
We consider renormalizability of topologically massive gravity in three space-time dimensions. With a usual parametrization of the metric tensor, we establish the statement that topologically massive gravity is in fact renormalizable. In this proof, we make use of not only a recently found, new infrared regularization method of scalar mode but also a covariant ultraviolet regulator with a speci...
متن کاملA note on positive energy of topologically massive gravity
I review how " classical SUGRA " embeddability establishes positive energy E for D = 3 topologically massive gravity (TMG), with or without a cosmological term, a procedure familiar from D = 4 Einstein gravity (GR). It also provides explicit expressions for E. In contrast to GR, E is not manifestly positive, due to the peculiar two-term nature of TMG.
متن کاملCircular symmetry in topologically massive gravity
We re-derive, compactly, a topologically massive gravity (TMG) decoupling theorem: source-free TMG separates into its Einstein and Cotton sectors for spaces with a hypersurface-orthogonal Killing vector, here concretely for circular symmetry. We then generalize the theorem to include matter; surprisingly, the single Killing symmetry also forces conformal invariance, requiring the sources to be ...
متن کاملQuasi-Normal Modes in Topologically Massive Gravity
We determine the black hole quasi-normal mode spectrum for tensor perturbations in topologically massive AdS-gravity. In the special case of chiral gravity quasi-normal modes are absent despite of the presence of a horizon. In the process we uncover a simple algebraic structure in the quasi normal modes spectrum: the tower of QNM’s consists of descendents of a ”chiral highest weight” QNM which ...
