Cosmological dynamics based on Lovelock's gravity. Qualitative analysis
Aleksei V. Nikolaev, Victor M. Zhuravlev, Sergei V. Chervon
We perform a complete qualitative analysis of the cosmological dynamics of Lovelock gravity in a spatially flat Friedmann-Robertson-Walker (FRW) universe filled with a perfect flui…
Universal cosmological solutions in Lovelock gravity
Aleksei Nikolaev
This paper explores the Friedmann field equations within the framework of Lovelock gravity, a natural extension of Einstein's gravity, focusing on both flat and open universes. Uti…
Kinetic Scalar Curvature Extended Gravity
S. V. Chervon, A. V. Nikolaev, T. I. Mayorova +2
In this work we study a modified version of vacuum gravity with a kinetic term which consists of the first derivatives of the Ricci scalar. We develop the general formalism…
Exact solutions for scalar field cosmology in f(R) gravity
S. D. Maharaj, R. Goswami, S. V. Chervon +1
We look for exact solutions in scalar field cosmology. To achieve this we use modified gravity with a scalar field and do not specify the the form of the function. In…
The effect of universe inhomogeneities on cosmological distance measurements
Aleksei Nikolaev, Sergey Chervon
Using the focusing equation, the equation for the cosmological angular diameter distance is derived, based on the ideas of Academician Ya.B. Zel'dovich, namely, that the distributi…
