Einstein-Yang-Mills Theory: Gauge Invariant Charges and Linearization Instability
Emel Altas, Ercan Kilicarslan, Bayram Tekin
We construct the gauge-invariant electric and magnetic charges in Yang-Mills theory coupled to cosmological General Relativity (or any other geometric gravity), extending the flat…
Energy and Angular Momentum in D dimensional Kerr-AdS black holes-new formulation
Emel Altas
Recently it was shown that the conserved charges of asymptotically anti de Sitter spacetimes can be written in an explicitly gauge-invariant way in terms of the linearized Riemann…
Second Order Gauge Invariant Perturbation Theory and Conserved Charges in Cosmological Einstein's Gravity
Emel Altas
Recently a new approach in constructing the conserved charges in cosmological Einstein's gravity was given. In this new formulation, instead of using the explicit form of the field…
Second Order Perturbation Theory in General Relativity: Taub Charges as Integral Constraints
Emel Altas, Bayram Tekin
In a nonlinear theory, such as General Relativity, linearized field equations around an exact solution are necessary but not sufficient conditions for linearized solutions. Therefo…
New approach to conserved charges of generic gravity in AdS
Emel Altas, Bayram Tekin
Starting from a divergence-free rank-4 tensor of which the trace is the cosmological Einstein tensor, we give a construction of conserved charges in Einstein's gravity and its high…
Conserved charges in AdS: A new formula
Emel Altas, Bayram Tekin
We give a new construction of conserved charges in asymptotically anti-de Sitter spacetimes in Einstein's gravity. The new formula is explicitly gauge-invariant and makes direct us…
Linearization Instability in Gravity Theories
Emel Altas
In a nonlinear theory, such as gravity, physically relevant solutions are usually hard to find. Therefore, starting from a background exact solution with symmetries, one uses the p…
Linearization Instability of Chiral Gravity
Emel Altas, Bayram Tekin
Carrying out an analysis of the constraints and their linearizations on a spacelike hypersurface, we show that topologically massive gravity has a linearization instability at the…
Linearization Instability for Generic Gravity in AdS
Emel Altas, Bayram Tekin
In general relativity, perturbation theory about a background solution fails if the background spacetime has a Killing symmetry and a compact spacelike Cauchy surface. This failure…
Holographically Viable Extensions of Topologically Massive and Minimal Massive Gravity?
Emel Altas, Bayram Tekin
Recently, an extension of the topologically massive gravity (TMG) in dimensions, dubbed as minimal massive gravity (MMG), was found which is free of the bulk-boundary unitari…
On Exact Solutions and the Consistency of 3D Minimal Massive Gravity
Emel Altas, Bayram Tekin
We show that all algebraic Type-O, Type-N and Type-D and some Kundt-Type solutions of Topologically Massive Gravity are inherited by its holographically well-defined deformation, t…
