We study the equivalence principle, regarded as the cornerstone of general relativity, by
analyzing the deformation observable of black hole shadows. Such deformation can arise …

Absolute parallelism geometry is frequently used for physical applications. It has two main
defects, from the point of view of applications. The first is the identical vanishing of its …

The gravitational field with torsion is being constructed by using the parametrized absolute
parallelism geometry. A generalized law of variation of Hubble's parameter in evolutionary …

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 …

Absolute parallelism (AP) geometry is frequently used for physical applications. Although it
is wider than the Riemannian geometry, it has two main defects. The first is that its path …

The discrepancy of $0.8% $ between theory and the COW-experiment is interpreted. This is
done by using a new path equation other than the geodesic one. It is shown that this …

Gravity is one of the four known fundamental interactions used to study and interpret
physical phenomenae. It governs diverse phenomenae, especially those connected with …

Paths in an appropriate geometry are usuallyused as trajectories of test particles in
geometrictheories of gravity. It is shown that non-symmetricgeometries possess some …

We analyze the four common types of finite-time singularity using a generic framework of the
phase portrait geometric approach. This technique requires the Friedmann system to be …

Raychaudhuri equation is generalized in the parametrized absolute parallelism geometry.
This version of absolute parallelism is more general than the conventional one. The …
