2+1-Gravity and The Embedding its Dynamiycal Symmetry and Para-Supersymmetry into SO(4,c) Group
M. A. Jafarizadeh, H. Fakhri, S. K. Moayedi
Some special solutions of the Einstein-Maxwell action with a non-negative cosmological constant and a very heavy point mass particle have been obtained. The solutions correspond to…
Tunneling in a Cosmological Model with Violation of Strong Energy Condition
M. A. Jafarizadeh, F. Darabi, A. Rezaei-Aghdam +1
The tunneling rate, with exact prefactor, is calculated to first order in \hbar for a closed FRW universe filled with perfect fluid violating the strong energy condition. The calcu…
On Duru-Kleinert Path Integral In Quantum Cosmology
M. A. Jafarizadeh, F. Darabi, A. R. Rastegar
We show that the Duru-Kleinert fixed energy amplitude leads to the path integral for the propagation amplitude in the closed FRW quantum cosmology with scale factor as one degree o…
Tunneling in Decaying Cosmologies and the Cosmological Constant Problem
M. A. Jafarizadeh, F. Darabi, A. Rezaei-Aghdam +1
The tunneling rate, with exact prefactor, is calculated to first order in for an empty closed Friedmann-Robertson-Walker (FRW) universe with decaying cosmological term $Λ\s…
