Noncommutative Quantum Cosmology
Luis O. Pimentel, Cesar Mora
We consider noncommutative quantum cosmology in the case of the low-energy string effective theory. Exacts solutions are found and compared with the commutative case.The Noncommuta…
Quantum Cosmology in Bergmann-Wagoner Scalar-tensor Gravitational Theory
Luis O. Pimentel, Cesar Mora
The Wheeler-DeWitt equation is solved for the Bergmann-Wagoner scalar-tensor gravitational theory in the case of Friedmann-Robertson- Walker cosmological model. We present solution…
Third Quantization of Brans-Dicke Cosmology
Luis O. Pimentel, Cesar Mora
We study the third quantization of a Brans-Dicke toy model, we calculate the number density of the universes created from nothing and found that it has a Planckian form. Also, we c…
Quantum Cosmology in some Scalar-tensor Theories
Luis O. Pimentel, César Mora
The Wheeler-DeWitt equation is solved for some scalar-tensor theories of gravitation in the case of homogeneous and isotropic cosmological models.We present general solutions corre…
Stationary Dilatons with Arbitrary Electromagnetic Field
Tonatiuh Matos, Cesar Mora
We present two new classes of axisymmetric stationary solutions of the Einstein-Maxwell-Dilaton equations with coupling constant . Both classes are written in terms of two h…
