Cosmographic Connection Between Cosmological And Planck Scales: The Barrow-Tsallis Entropy
Yu. L. Bolotin, V. V. Yanovsky, D. A. Yerokhin
One of the fundamental challenges of quantum gravity is to understand how the microscopic degrees of freedom of the cosmological horizon shape the evolution of the Universe. One po…
Barrow entropy and spacetime foam
Yu. L. Bolotin, V. V. Yanovsky
Quantum gravitational effects, on the one hand, lead to a limitation in the accuracy of measuring spatial and time intervals, and, on the other hand, they generate a discrete of sp…
Note on cosmographic approach to determining parameters of Barrow entropic dark energy model
Yu. L. Bolotin, V. V. Yanovsky
The cosmographic approach is used to determine the parameters of the Barrow entropic dark energy model. The model parameters are expressed through the current kinematic characteris…
Do current observations support transient acceleration of our universe?
Yu. L. Bolotin, V. A. Cherkaskiy, M. I. Konchatnyi +2
In the present article we have investigated a very natural question regarding the dynamics of the universe, namely, the possibility of its decelerating phase immediately after the…
APPLIED COSMOGRAPHY: A Pedagogical Review
Yu. L. Bolotin, V. A. Cherkaskiy, O. Yu. Ivashtenko +2
Based on the cosmological principle only, the method of describing the evolution of the Universe, called cosmography, is in fact a kinematics of cosmological expansion. The effecti…
Cosmography of Cardassian model
Yu. L. Bolotin, M. I. Konchatnyi, O. A. Lemets +1
The parameters of any model that satisfies the cosmological principle (the universe is homogeneous and isotropic on large scale), can be expressed through cosmographic parameters.…
Modified Planck units
Yu. L. Bolotin, V. V. Yanovsky
Planck units are natural physical scales of mass, length and time, built with the help of the fundamental constants . The functional role of the constants used for the…
Cosmology In Terms Of The Deceleration Parameter. Part II
Yu. L. Bolotin, V. A. Cherkaskiy, O. A. Lemets +2
In the early seventies, Alan Sandage defined cosmology as the search for two numbers: Hubble parameter and deceleration parameter . The first of the two basi…
New Cosmographic Constraints on the Dark Energy and Dark Matter Coupling
Yu. L. Bolotin, V. A. Cherkaskiy, O. A. Lemets
We consider three cosmological models with linear interaction between the dark components and obtain restrictions on the coupling constant in terms of the cosmographic parameters.…
Cosmology In Terms Of The Deceleration Parameter. Part I
Yu. L. Bolotin, V. A. Cherkaskiy, O. A. Lemets +2
In the early seventies, Alan Sandage defined cosmology as the search for two numbers: Hubble parameter and deceleration parameter . The first of the two basi…
A Thousand Problems in Cosmology: Interaction in the Dark Sector
Yu. L. Bolotin, V. A. Cherkaskiy, O. A. Lemets +2
This is one chapter of the collection of problems in cosmology, in which we assemble the problems that concern one of the most distinctive features of modern cosmology---the intera…
A Thousand Problems in Cosmology: Horizons
Yu. L. Bolotin, I. V. Tanatarov
This is one chapter of the collection of problems in cosmology, in which we assemble the problems, with solutions, that concern one of the most distinctive features of general rela…
Cosmological Evolution With Interaction Between Dark Energy And Dark Matter
Yu. L. Bolotin, A. Kostenko, O. A. Lemets +1
In this review we consider in detail different theoretical topics associated with interaction in the dark sector. We study linear and nonlinear interactions which depend on the dar…
A Thousand Problems in Cosmology. Chapter 4: Black holes
Yu. L. Bolotin, I. V. Tanatarov, O. B. Zaslavskii
The fourth chapter of the collection of problems in cosmology, devoted to black holes. Consists of basic introduction, sections on Schwarzschild and Kerr black holes, a section on…
Holographic Dynamics as Way to Solve the Basic Cosmological Problems
Yu. L. Bolotin, O. A. Lemets, D. A. Yerokhin +1
We review recent results on the cosmological models based on the holographic principle which were proposed to explain the most of the problems occurring in the Standard Cosmologica…
Expanding Universe: slowdown or speedup?
Yu. L. Bolotin, O. A. Lemets, D. A. Yerokhin
The kinematics and dynamic interpretation of the cosmological expansion is reviewed in a widely accessible manner with emphasis on the acceleration aspect. Virtually all the approa…
Dynamics of the Universe in Problems
Yu. L. Bolotin, V. A. Cherkaskiy, G. I. Ivashkevych +3
To our best knowledge, there are no problem books on cosmology yet, that would include its spectacular recent achievements. We believe there is a strong need for such now, when cos…
Decay of the Mixed States
Yu. L. Bolotin, V. A. Cherkaskiy, G. I. Ivashkevych
We study the classical escape from local minima for 2d multi-well Hamiltonian systems, realizing the mixed state. We show that escape from such local minima has a diversity of prin…
