Cosmological constraints on time-varying cosmological terms: A study of FLRW universe models with CDM cosmology
M. Koussour, N. Myrzakulov, J. Rayimbaev
This paper explores models of the FLRW universe that incorporate a time-varying cosmological term . Specifically, we assume a power-law form for the cosmological term as a fu…
Probing Weyl-type gravity: Cosmological implications and constraints
Alnadhief H. A. Alfedeel, M. Koussour, N. Myrzakulov
In this paper, we investigate the cosmological implications and constraints of Weyl-type gravity. This theory introduces a coupling between the non-metricity and the…
Non-minimal geometry-matter couplings in Weyl-Cartan space-times: gravity
Tiberiu Harko, Nurgissa Myrzakulov, Ratbay Myrzakulov +1
We consider an extension of standard General Relativity in which the Hilbert-Einstein action is replaced by an arbitrary function of the Ricci scalar, nonmetricity, torsion, and th…
Metric-Affine Version of Myrzakulov Gravity and Cosmological Applications
Damianos Iosifidis, Nurgissa Myrzakulov, Ratbay Myrzakulov
We derive the full set of field equations for the Metric-Affine version of the Myrzakulov gravity model and also extend this family of theories to a broader one. More specifically,…
Tachyon field non-minimally coupled to massive neutrino matter
Safia Ahmad, Nurgissa Myrzakulov, R. Myrzakulov
In this paper, we consider rolling tachyon, with steep run-away type of potentials non-minimally coupled to massive neutrino matter. The coupling dynamically builds up at late time…
Some Models of Cyclic and Knot Universes
K. R. Yesmakhanova, N. A. Myrzakulov, K. K. Yerzhanov +3
In this paper, we obtained a class of oscillatory, cyclic and knot type solutions from the non-linear Friedmann equations. This is performed by choosing specific forms of energy de…
Dark energy in some integrable and nonintegrable FRW cosmological models
Kuralay Esmakhanova, Nurgissa Myrzakulov, Gulgasyl Nugmanova +3
One of the greatest challenges in cosmology today is to determine the nature of dark energy, the sourse of the observed present acceleration of the Universe. Besides the vacuum ene…
