Noncommutative cosmological models coupled to a perfect fluid and a cosmological constant
E. M. C. Abreu, M. V. Marcial, A. C. R. Mendes +2
In this work we carry out a noncommutative analysis of several Friedmann-Robert-Walker models, coupled to different types of perfect fluids and in the presence of a cosmological co…
Can noncommutativity affect the whole history of the Universe?
G. A. Monerat, E. V. Corrêa Silva, C. Neves +3
We study a classical, noncommutative (NC), Friedmann-Robertson-Walker cosmological model. The spatial sections may have positive, negative or zero constant curvatures. The matter c…
An Early Universe Model with Stiff Matter and a Cosmological Constant
G. Oliveira-Neto, G. A. Monerat, E. V. Corrêa Silva +2
In the present work, we study the quantum cosmology description of a Friedmann-Robertson-Walker model in the presence of a stiff matter perfect fluid and a negative cosmological co…
