Anisotropic singularities in chiral modified gravity
Yannick Herfray, Kirill Krasnov, Yuri Shtanov
In four space-time dimensions, there exists a special infinite-parameter family of chiral modified gravity theories. All these theories describe just two propagating polarizations…
Arrow of time in dissipationless cosmology
Varun Sahni, Yuri Shtanov, Aleksey Toporensky
It is generally believed that a cosmological arrow of time must be associated with entropy production. Indeed, in his seminal work on cyclic cosmology, Tolman introduced a viscous…
Dark Energy: Observational Evidence and Theoretical Models
B. Novosyadlyj, V. Pelykh, Yu. Shtanov +1
The book elucidates the current state of the dark energy problem and presents the results of the authors, who work in this area. It describes the observational evidence for the exi…
