Non-stationary Energy in General Relativity
Emel Altas, Bayram Tekin
Using the time evolution equations of (cosmological) General Relativity in the first order Fischer-Marsden form, we construct an integral that measures the amount of non-stationary…

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…
