Abilities of multidimensional gravity
K. A. Bronnikov, S. G. Rubin
We show that a number of problems of modern cosmology may be addressed and solved in the framework of multidimensional gravity with high-order curvature invariants, without invokin…
Matter sources for a Null Big Bang
K. A. Bronnikov, O. B. Zaslavskii
We consider the properties of stress-energy tensors compatible with a Null Big Bang, i.e., cosmological evolution starting from a Killing horizon rather than a singularity. For Kan…
Global strings in extra dimensions: a full map of solutions, matter trapping and the hierarchy problem
K. A. Bronnikov, B. E. Meierovich
We consider (d_0+2)-dimensional configurations with global strings in the two extra dimensions and a flat metric in d_0 dimensions, endowed with a warp factor e^{2γ} depending on t…
Regular homogeneous T-models with vacuum dark fluid
K. A. Bronnikov, I. G. Dymnikova
We present the class of regular homogeneous T-models with vacuum dark fluid, associated with a variable cosmological term. The vacuum fluid is defined by the symmetry of its stress…
Charged black holes and unusual wormholes in scalar-tensor gravity
K. A. Bronnikov, M. S. Chernakova
We consider static, spherically symmetric, electrically or/and magnetically charged configurations of a minimally coupled scalar field with an arbitrary potential in general…
