Noether and Mei symmetries in static spherically symmetric quadratic gravity: variational consistency, constraints, and conserved curvature flux
G. G. N. Nashed, A. Eid, Kazuharu Bamba
The symmetry content of static spherical gravity is reconsidered for the pure quadratic model. We first derive the radial action without prematurely eliminating the equation…

Holographic Dark Energy as a Source for Wormholes in Modified Gravity
G. G. L. Nashed, A. Eid
Traversable wormhole solutions are explored in gravity, a curvature--matter extension in which is the Ricci scalar and denote…

Four-scalar model and spherically symmetric solution in theory
G. G. L. Nashed, A. Eid
In this work, we investigate the construction of spherically symmetric solutions within the framework of modified teleparallel gravity, focusing in particular on theo…
