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.…

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.…

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…

Interacting dark energy models in fractal cosmology

O. A. Lemets, D. A. Yerokhin

We investigate interacting dark energy models in the framework of fractal cosmology. We discuss a fractal FRW universe filled with the dark energy and dark matter which interact wi…
