On The splitting of the Einstein field equations with respect to a general threading of spacetime
Aurel Bejancu, Hani Reda Farran
Based on a general threading of the spacetime , we obtain a new and simple splitting of a both the Einstein field equations (EFE) and the conservation laws in $(M,g)…

Kinematic Quantities and Raychaudhuri Equations in a Universe
Aurel Bejancu
Based on some ideas emerged from the classical Kaluza-Klein theory, we present a universe as a product bundle over the spacetime. This enables us to introduce and study t…

On the (1+3) threading of spacetime with respect to an arbitrary timelike vector field
Aurel Bejancu, Constantin Călin
We develop a new approach on the (1+3) threading of spacetime with respect to a congruence of curves defined by an arbitrary timelike vector field. The study is based on s…
