Cosmic Acceleration and Extra Dimensions
Varun Sahni, Yuri Shtanov
Brane cosmology presents many interesting possibilities including: phantom acceleration (w<-1), self-acceleration, unification of dark energy with inflation, transient acceleration…
Asymmetric embedding in brane cosmology
Yuri Shtanov, Alexander Viznyuk, Luis Norberto Granda
We derive a system of cosmological equations for a braneworld with induced curvature which is a junction between several bulk spaces. The permutation symmetry of the bulk spaces is…
Boiling of nuclear liquid in core-collapse supernova explosions
Peter Fomin, Dmytro Iakubovskyi, Yuri Shtanov
We investigate the possibility of boiling instability of nuclear liquid in the inner core of the proto-neutron star formed in the core collapse of a type II supernova. We derive a…
Spherically symmetric problem on the brane and galactic rotation curves
Alexander Viznyuk, Yuri Shtanov
We investigate the braneworld model with induced gravity to clarify the role of the cross-over length scale \ell in the possible explanation of the dark-matter phenomenon in astrop…
Non-Metric Gravity II: Spherically Symmetric Solution, Missing Mass and Redshifts of Quasars
Kirill Krasnov, Yuri Shtanov
We continue the study of the non-metric theory of gravity introduced in hep-th/0611182 and gr-qc/0703002 and obtain its general spherically symmetric vacuum solution. It respects t…
Gravitational instability on the brane: the role of boundary conditions
Yuri Shtanov, Alexander Viznyuk, Varun Sahni
An outstanding issue in braneworld theory concerns the setting up of proper boundary conditions for the brane-bulk system. Boundary conditions (BC's) employing regulatory branes or…
