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…
