In this review we discuss the evolution of the universe filled with dark energy with or without
perfect fluid. In doing so we consider a number of cosmological models, namely Bianchi type …

A system of minimally coupled nonlinear spinor and scalar fields within the scope of a
Bianchi type-I (BI) cosmological model in the presence of a perfect fluid and a cosmological …

Within the scope of the isotropic FRW cosmological model the role of nonlinear spinor field
in the evolution of the Universe is studied. It is found that unlike in anisotropic cosmological …

Within the scope of Bianchi type VI, VI0, V, III, I, LRSBI and FRW cosmological models we
have studied the role of nonlinear spinor field on the evolution of the Universe and the …

We have obtained exact static plane-symmetric solutions to the spinor field equations with
nonlinear terms which are arbitrary functions of invariant, taking into account their own …

In this paper we investigate a class of solutions of Einstein equations for the plane-
symmetric perfect fluid case with shear and vanishing acceleration. If these solutions have …

The present research work is considered as part II of the previous work entitled [Plane
Symmetric Solutions to the Nonlinear Spinor Field Equations in General Relativity Theory …

In the present research work, we have obtained the exact spherical symmetric solutions of
Heisenberg-Ivanenko nonlinear spinor field equations in the Gravitational Theory. The …

Within the scope of Bianchi type-VI 0 spacetime we study the role of spinor field on the
evolution of the Universe. It is found that the presence of the non-trivial non-diagonal …

The present research work deals with an extension of a previous work entitled [Exact Soliton-
like spherical symmetric solutions of the Heisenberg-Ivanenko type nonlinear spinor field …
