Resonances in the early Universe
D. L. Canedo, G. Oliveira-Neto, G. A. Monerat +1
In the present paper, we study a Friedmann-Lemaître-Robertson-Walker (FLRW) quantum cosmology model with positively curved spatial sections. The matter content of the model is give…

Quantization of Friedmann-Robertson-Walker spacetimes in the presence of a negative cosmological constant and radiation
G. A. Monerat, E. V. Correa Silva, G. Oliveira-Neto +2
We quantize three Friedmann-Robertson-Walker models in the presence of a negative cosmological constant and radiation. The models differ from each other by the constant curvature o…
