On the energy of a non-singular black hole solution satisfying the weak energy condition
I. Radinschi, Th. Grammenos, F. Rahaman +3
The energy-momentum localization for a new four-dimensional and spherically symmetric, charged black hole solution that through a coupling of general relativity with non-linear ele…
Localization of Energy-Momentum for a Black Hole Spacetime Geometry with Constant Topological Euler Density
Irina Radinschi, Theophanes Grammenos, Farook Rahaman +4
The evaluation of the energy-momentum distribution for a new four-dimensional, spherically symmetric, static and charged black hole spacetime geometry with constant non-zero topolo…
Energy-momentum for a charged nonsingular black hole solution with a nonlinear mass function
I. Radinschi, Th. Grammenos, Farook Rahaman +4
The energy-momentum of a new four-dimensional, charged, spherically symmetric and nonsingular black hole solution constructed in the context of general relativity coupled to a theo…
Towards Canonical Quantum Gravity for G1 Geometries in 2+1 Dimensions with a Lambda--Term
T. Christodoulakis, G. Doulis, Petros A Terzis +4
The canonical analysis and subsequent quantization of the (2+1)-dimensional action of pure gravity plus a cosmological constant term is considered, under the assumption of the exis…
Decoupling of the general scalar field mode and the solution space for Bianchi type I and V cosmologies coupled to perfect fluid sources
T. Christodoulakis, Th. Grammenos, Ch. Helias +2
The scalar field degree of freedom in Einstein's plus Matter field equations is decoupled for Bianchi type I and V general cosmological models. The source, apart from the minimally…
