Energy-momentum complexes in f(R) theories of gravity
Tuomas Multamaki, Antti Putaja, Elias C. Vagenas +1
Despite the fact that modified theories of gravity, in particular the f(R) gravity models have attracted much attention in the last years, the problem of the energy localization in…
Gravitational anomalies: a recipe for Hawking radiation
Saurya Das, Sean P. Robinson, Elias C. Vagenas
We explore the method of Robinson and Wilczek for deriving the Hawking temperature of a black hole. In this method, the Hawking radiation restores general covariance in an effectiv…
The Cosmological Dynamics of Interacting Holographic Dark Energy Model
M. R. Setare, Elias C. Vagenas
Motivated by the recent observations for the cosmic acceleration and the suitable evolution of the Universe provided an interaction (decay of dark energy to matter) is incorporated…
