Motion of Spinning and Spinning Deviation Density Tensors in Riemannian Geometry
Magd E. Kahil, Samah A. Ammar, Shymaa A. Refaey
Equations of motion of spinning density for extended objects, and corresponding deviation equations are derived. The problem of motion for a variable mass to a spinning extended ob…

Space-Time Structure and Electromagnetism
M. I. Wanas, Samah A. Ammar
Two Lagrangian functions are used to construct geometric field theories. One of these Lagrangians depends on the curvature of space, while the other depends on curvature and torsio…
