Einstein Geometrization Philosophy and Differential Identities in PAP-Geometry
M. I. Wanas, Nabil L. Youssef, W. El Hanafy +1
The importance of Einstein's geometrization philosophy, as an alternative to the least action principle, in constructing general relativity (GR), is illuminated. The role of differ…
Gravity theory in SAP-geometry
Nabil L. Youssef, Amr M. Sid-Ahmed, Ebtsam H. Taha
The aim of the present paper is to construct a field theory in the context of absolute parallelism (Teleparallel) geometry under the assumption that the canonical connection is sem…
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 Global Approach to Absolute Parallelism Geometry
Nabil L. Youssef, Waleed A. Elsayed
In this paper we provide a \emph{global} investigation of the geometry of parallelizable manifolds (or absolute parallelism geometry) frequently used for application. We discuss th…
Telleparallel Lagrange Geometry and a Unified Field Theory: Linearization of the Field Equations
M. I. Wanas, Nabil L. Youssef, A. M. Sid-Ahmed
The present paper is a natural continuation of our previous paper: "Teleparallel Lagrange geometry and a unified field theory, Class. Quantum Grav., 27 (2010), 045005 (29pp)" \cite…
Teleparallel Lagrange Geometry and a Unified Field Theory
M. I. Wanas, Nabil L. Youssef, A. M. Sid-Ahmed
In this paper, we construct a field theory unifying gravity and electromagnetism in the context of Extended Absolute Parallelism (EAP-) geometry. This geometry combines, within its…
