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…
