Phase Portraits of general f(T) Cosmology
A. Awad, W. El Hanafy, G. G. L. Nashed +1
We use dynamical system methods to explore the general behaviour of cosmology. In contrast to the standard applications of dynamical analysis, we present a way to transform…
Constant-roll Inflation in Teleparallel Gravity
A. Awad, W. El Hanafy, G. G. L. Nashed +2
We investigate in detail the implications of the constant-roll condition on the inflationary era of a scalar field coupled to a teleparallel gravity. The resulting cosmologi…
Generic Phase Portrait Analysis of the Finite-time Singularities and Generalized Teleparallel Gravity
W. El Hanafy, G. G. L. Nashed
We analyze the common four types of the finite-time singularities using a generic framework of the phase portrait geometric approach. This technique requires that the Friedmann sys…
Analytic rotating black hole solutions in -dimensional gravity
G. G. L. Nashed, W. El Hanafy
A non-diagonal vielbein ansatz is applied to the -dimension field equations of gravity. An analytical vacuum solution is derived for the quadratic polynomial $f(T)=T+εT^2…
