Symmetry and Conserved Quantities in -Gravity: Mei vs. Noether Approaches
Tahia F. Dabash, Moataz H. Emam, Lukas Schoppner
We study the symmetries and conserved quantities in gravity for the static, spherically symmetric Reissner--Nordström spacetime using two complementary frameworks: Noether…

Parameterized Evolution of the Kretschmann Scalar in Friedmann-Lemaitre-Robertson-Walker Cosmology with Torsion Contributions and Big Rip Model
Tahia F. Dabash, M. A. Bakry
We investigate the Kretschmann scalar within the framework of Parameterized Absolute Parallelism (PAP) geometry, extending the classical understanding of spacetime curvature in Gen…

The geodesic structure of BPS one-branes in five dimensions
Tahia F. Dabash, Moataz H. Emam
In this paper, we continue previous work where one-brane spacetimes coupled to the N=2 ungauged five dimensional hypermultiplets were found. We explore their symmetries as well as…
