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 s…
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…
Interpreting the Cosmic History of the Universe Through Five-Dimensional Supergravity
Moataz H. Emam, Safinaz Salem
Through modeling the universe as a symplectic 3-brane embedded in the bulk of N = 2 five-dimensional ungauged supergravity theory, the entire evolution of the universe can be inter…
The Implications of N = 2 Supergravity Cosmology On the Topology of the Calabi-Yau Manifold
Safinaz Salem, Moataz H. Emam, H. H. Salah
When N= D=11 supergravity is compactified on CY threefold to N=2 D=5 supergravity the action of the last is given in terms of the geometery of the CY manifold space, namely, in ter…
Brane-Worlds and the Calabi-Yau Complex Structure Moduli
Moataz H. Emam, H. H. Salah, Safinaz Salem
In this paper we extend previous work on the relation between the complex structure moduli of the underlying Calabi-Yau manifold in five dimensional supergravity with the time evol…
BPS brane cosmology in N=2 supergravity
Moataz H. Emam
We study the embedding of flat BPS 3-branes in five dimensional N=2 supergravity theory. We derive the branes' dynamical equations as well as general expressions for the hypermulti…
