Distribution of EnergyMomentum in a SchwarzschildQuintessence SpaceTime Geometry
Radinschi, I.; Grammenos, T.; Spanou, A. (2013)An analysis of the energymomentum localization for a fourdimensional Schwarzschild black hole surrounded by dark energy in the form of quintessence is presented in order to provide expressions for the distributions of ... 
Energy distribution in a Schwarzschildlike spacetime
Grammenos, T.; Radinschi, I. (2007)In this paper, utilizing Moller's energymomentum complex, we explicitly evaluate the energy and momentum density associated with a metric describing a fourdimensional, Schwarzschildlike, spacetime derived from an effective ... 
Energy Distribution of a Regular Black Hole Solution in EinsteinNonlinear Electrodynamics
Radinschi, I.; Rahaman, F.; Grammenos, T.; Spanou, A.; Islam, S. (2015)A study about the energy momentum of a new fourdimensional spherically symmetric, static and charged, regular black hole solution developed in the context of general relativity coupled to nonlinear electrodynamics is ... 
Energy distribution of the EinsteinKleinGordon system for a static spherically symmetric spacetime in (2+1) dimensions
Radinschi, I.; Grammenos, T. (2006)We use Moller's energymomentum complex in order to explicitly compute the energy and momentum density distributions for an exact solution of Einstein's field equations with a negative cosmological constant, minimally ... 
ENERGY LOCALIZATION FOR DILATONIC BLACK HOLE GEOMETRIES WITH A PURE MONOPOLE FIELD
Radinschi, I.; Grammenos, T. (2010)The energy distribution of black holes with a dilaton and a pure monopole field is calculated by using Moller's energymomentum complex. The fourdimensional spacetimes considered are static, spherically symmetric and ... 
Energymomentum complexes for a stringy black hole geometry in a lowenergy effective string theory
Radinschi, I.; Grammenos, T. (2009)The energy and momentum distributions for a fourdimensional, magnetically charged, stringy black hole geometry, in a lowenergy effective string theory, are calculated. To this purpose, the energymomentum complexes of ... 
EnergyMomentum Localization for a SpaceTime Geometry Exterior to a Black Hole in the Brane World
Radinschi, I.; Grammenos, T.; Spanou, A. (2013)In general relativity one of the most fundamental issues consists in defining a generally acceptable definition for the energymomentum density. As a consequence, many coordinatedependent definitions have been presented, ... 
Localization of energy for a regular black hole solution in an asymptotically de Sitter spacetime geometry
Radinschi, I.; Grammenos, T.; Spanou, A. (2011)The energy and momentum distributions of a regular black hole in a fourdimensional, asymptotically de Sitter spacetime geometry are computed, whereby the Einstein, LandauLifshitz, Weinberg and Moller energymomentum ... 
Moller's energymomentum complex for a spacetime geometry on a noncommutative curved D3brane
Radinschi, I.; Grammenos, T. (2008)Moller's energymomentum complex is employed in order to determine the energy and momentum distributions for a spacetime described by a "generalized Schwarzschild" geometry in (3+1)dimensions on a noncommutative curved ...
