In recent years, the discrepancy in the value of the Hubble parameter has been growing.
Recently, there are works supporting the proposal that the uncertainty principles can solve …

We start by presenting a brief summary of fractional quantum mechanics, as means to
convey a motivation towards fractional quantum cosmology. Subsequently, such application …

We analyze the global nonlinear stability of FLRW (Friedmann-Lemaître-Robertson-Walker)
spacetimes in the presence of an irrotational perfect fluid. We assume that the fluid is …

We investigate the quantum cosmology of a closed spatially homogeneous and isotropic
Friedmann–Lemaître–Robertson–Walker (FLRW) minisuperspace model with …

We review pedagogically some of the basic essentials regarding recent results intertwining
boundary conditions, the algebra of constraints and hidden symmetries in quantum …

We establish the future nonlinear stability of Friedmann–Lemaître–Robertson–Walker
(FLRW) solutions to the Einstein–Euler equations of the universe filled with a large class of …

We describe the linear cosmological perturbations of a perfect fluid at the level of an action,
providing thus an alternative to the standard approach based only on the equations of …

“Like revealing all details of a coastal area merely through an holiday postcard”, a friend
once commented on what quantum cosmology (QC) seemed. Properly identified detailed …

We study the effects of a generalized uncertainty principle on the classical and quantum
cosmology of a closed Friedmann universe whose matter content is either a dust or a …

We consider a Bianchi type III axisymmetric geometry in the presence of an electromagnetic
field. A first result at the classical level is that the symmetry of the geometry need not be …
