We study the dynamics of the field equations in a four-dimensional isotropic and
homogeneous spatially flat Friedmann-Lemaître-Robertson-Walker geometry in the context …

In the framework of Saez–Ballester (SB) theory, the current study proposes a reconstruction
scheme for Tsallis and Kaniadakis holographic dark energy, particular cases of a more …

In the context of the modified teleparallel f (T, B) theory of gravity, we consider a
homogeneous and anisotropic background geometry described by the Kantowski–Sachs …

In this paper, a non‐interacting scalar field cosmology with an arbitrary potential using the f‐
deviser method that relies on the differentiability properties of the potential is investigated …

In this paper, we study a cosmological model inspired in the axionic matter with two
canonical scalar fields ϕ 1 and ϕ 2 interacting through a term added to its potential …

This research focuses on scalar field cosmologies with a generalized harmonic potential.
Our attention is centred on the anisotropic LRS Bianchi I and III metrics, Bianchi V metrics …

Scalar field cosmologies with a generalized harmonic potential are investigated in flat and
negatively curved Friedmann–Lemaître–Robertson–Walker and Bianchi I metrics. An …

We introduce a time-delay function in bulk viscosity cosmology. Even for bulk viscosity
functions where closed-form solutions are known, because of the time-delay term, the exact …

The scope of this thesis is the analysis of cosmological models arising from Einstein's theory
of General Relativity. Motivated by cosmological models of the early universe we focus on …
