Graceful Exit Inflation in Gravity
G. G. L. Nashed, W. El Hanafy, Sh. Kh. Ibrahim
We apply a quadratic teleparallel torsion scalar of the field equations to the spatially flat Friedmann-Robertson-Walker (FRW) model. We assume two perfect fluid co…
Reconstruction of -gravity in the absence of matter
W. El Hanafy, G. L. Nashed
We derive an exact gravity in the absence of ordinary matter in Friedmann-Robertson-Walker (FRW) universe, where is the teleparallel torsion scalar. We show that vanishi…
The Hidden Flat Like Universe: Starobinsky-like inflation induced by f(T) gravity
W. El Hanafy, G. G. L. Nashed
We study a single fluid component in a flat like universe (FLU) governed by gravity theories, where is the teleparallel torsion scalar. The FLU model, regardless the val…
Pure Geometric Field Theory: Description of Gravity and Material Distribution
M. I. Wanas, Nabil L. Youssef, W. El Hanafy
A field theory is constructed in the context of parameterized absolute parallelism geometry. The theory is shown to be a pure gravity one. It is capable of describing the gravitati…
A Built-in Inflation in the -Cosmology
G. G. L. Nashed, W. El Hanafy
In the present work we derive an exact solution of an isotropic and homogeneous Universe governed by gravity. We show how the torsion contribution to the FRW cosmology can p…
