On the thin wall limit of thick planar domain walls
S. Ghassemi, S. Khakshournia, R. Mansouri
Considering a planar gravitating thick domain wall of the theory, we demonstrate how the Darmois junction conditions written on the boundaries of the thick wall with the emb…
Dynamics of a Spherical Null Shell within the Distributional Formalism
Samad Khakshournia, Reza Mansouri
Dynamics of a null thin shell immersed in a generic spherically symmetric spacetime is obtained within the distributional formalism. It has been shown that the distributional forma…
Dynamics of general relativistic spherically symmetric dust thick shells
Samad Khakshournia, Reza Mansouri
We consider a spherical thick shell immersed in two different spherically symmetric space-times. Using the fact that the boundaries of the thick shell with two embedding space-time…
Signature Change, Inflation, and the Cosmological Constant
Reza Mansouri, Kourosh Nozari
Colombeau's generalized functions are used to adapt the distributional approach to singular hypersurfaces in general relativity with signature change. Equations governing the dynam…
Application of Colombeau's Generalized Functions to Cosmological Models with Signature Change
Reza Mansouri, Kourosh Nozari
Colombeau's generalized functions are used to adapt the distributional approach to singular hypersurfaces in general relativity with signature change. Equations governing the dynam…
Rotation of Plane of Polarization of an Electromagnetic Wave Propagating over Cosmological Distances in "Finite Rotating Universe" Scenario
R. Mansouri, K. Nozari
A systematic rotation of the plane of polarization of electromagnetic radiation propagating over cosmological distances has been claimed to be detected by Nodland and Ralston.Takin…
