We review analytical solutions of the Einstein equations which are expressed in terms of
elementary functions and describe Friedmann–Lemaître–Robertson–Walker universes …

The purpose of this paper is to uncover a connection between the dynamics associated with
cosmological models and the radially symmetric nonlinear Schrödinger (NLS) equation. The …

We report a method of solving for canonical scalar field exact solution in a non-flat FLRW
universe with barotropic fluid using non-linear Schrödinger (NLS)-type formulation in …

Methods for obtaining exact solutions of the dynamical equations in Friedmann–Robertson–
Walker spacetime for cosmological models with a scalar field and matter fields or nonzero …

Time-independent nonlinear Schrödinger-type (NLS) formulation of FRW cosmology with
canonical scalar field is considered in the case of two barotropic fluids. We derived …

We describe non-flat standard Friedmann cosmology of canonical scalar field with
barotropic fluid in form of non-linear Schrödinger-type (NLS) formulation in which all …

A simple model is investigated according to which the deformation of the vacuum
corresponding to the localization of a particle is described by particular solutions of an …
