Analytical Theory of Optical Black Hole Analogues
Suraj S. Hegde, C. V. Vishveshwara
We develop an analytical formalism for studying optical analogues of spherically symmetric black-hole spacetimes. We demonstrate the exact similarity between the electromagnetic wa…
Black Holes in Non-flat Backgrounds: the Schwarzschild Black Hole in the Einstein Universe
K. Rajesh Nayak, M. A. H. MacCallum, C. V. Vishveshwara
As an example of a black hole in a non-flat background a composite static spacetime is constructed. It comprises a vacuum Schwarzschild spacetime for the interior of the black hole…
Gyroscopic Precession and Inertial Forces in Axially Symmetric Stationary Spacetimes
K. Rajesh Nayak, C. V. Vishveshwara
We study the phenomenon of gyroscopic precession and the analogues of inertial forces within the framework of general relativity. Covariant connections between the two are establis…
The Frenet Serret Description of Gyroscopic Precession
B. R. Iyer, C. V. Vishveshwara
The phenomenon of gyroscopic precession is studied within the framework of Frenet-Serret formalism adapted to quasi-Killing trajectories. Its relation to the congruence vorticity i…
