A Type D Non-Vacuum Spacetime with Causality Violating Curves, and its Physical Interpretation
Faizuddin Ahmed
We present a topologically trivial, non-vacuum solution of the Einstein's field equations in four-dimensions, which is regular everywhere. The metric admits circular closed timelik…

Axially Symmetric Null dust Spacetime, Naked Singularity and Cosmic Time Machine
Faizuddin Ahmed
In this article, we present a gravitational collapse null dust solution of the Einstein field equations. The spacetime is regular everywhere except on the symmetry axis where it po…

Cylindrical symmetry locally isometric spacetime
Faizuddin Ahmed, Davood Momeni, Debojit Sarma +2
We present a maximally symmetric vacuum spacetime, which is locally isometric anti- de Sitter, admitting closed timelike curves appear after a definite instant of time i.e., a time…
