In the isotropic quantum cosmological perfect fluid model, the initial singularity can be avoided, while the classical behaviour is recovered asymptotically. We verify if initial anisotropies can also be suppressed in a quantum version of a classical anisotropic model where gravity is coupled to a perfect fluid. Employing a Bianchi I cosmological model, we obtain a "Schr\"odinger-like" equation where the matter variables play de role of time. This equation has a hyperbolic signature. It can be… 
Quantum cosmology from the de Broglie–Bohm perspective
We review the main results that have been obtained in quantum cosmology from the perspective of the de Broglie?Bohm quantum theory. As it is a dynamical theory of assumed objectively real
QUANTUM PERFECT-FLUID KALUZA–KLEIN COSMOLOGY
The perfect-fluid cosmology in the (1+d+D)-dimensional Kaluza–Klein space–times for an arbitrary barotropic equation of state p = (γ-1)ρ is quantized by using the Schutz's variational formalism. We
Noncommutative quantum mechanics and Bohm's ontological interpretation
We carry out an investigation into the possibility of developing a Bohmian interpretation based on the continuous motion of point particles for noncommutative quantum mechanics. The conditions for
A Bohmian interpretation for noncommutative quantum field theory and quantum mechanics
We develop Bohmian interpretations for noncommutative quantum field theory and quantum mechanics. The conditions for the classical and commutative limits for both theories are derived and applied for

Canonical quantum gravity and the problem of time
The aim of this paper is to provide a general introduction to the problem of time in quantum gravity. This problem originates in the fundamental conflict between the way the concept of ‘time’ is used
