Phantom phase power-law solution in gravity
A. R. Rastkar, M. R. Setare, F. Darabi
Power-law solutions for gravity coupled with perfect fluid have been studied for spatially flat universe. It is shown that despite the matter dominated and accelerating powe…
Classification of real three-dimensional Lie bialgebras and their Poisson-Lie groups
A. Rezaei-Aghdam, M. Hemmati, A. R. Rastkar
Classical r-matrices of the three-dimensional real Lie bialgebras are obtained. In this way all three-dimensional real coboundary Lie bialgebras and their types (triangular, quasit…
Noncommutativity in quantum cosmology and the Hierarchy problem
F. Darabi, A. Rezaei-Aghdam, A. R. Rastkar
We study the quantum cosmology of an empty (4+1)-dimensional Kaluza-Klein cosmology with a negative cosmological constant and a FRW type metric with two scale factors, one for 4-D…
A quantum cosmology and discontinuous signature changing classical solutions
F. Darabi, A. Rastkar
We revisit the classical and quantum cosmology of a universe in which a self interacting scalar field is coupled to gravity with a flat FRW type metric undergoing continuous signat…
