A Note on Stress-Energy Tensor and Variational Principle for Null Strings
E. A. Davydov, D. V. Fursaev, V. A. Tainov
A straightforward application of the variational principle to null strings meets difficulties since string's world-sheets are degenerate. It is known that the variational principle…
Null Cosmic Strings: Scattering by Black Holes, Optics and Spacetime Content
E. A. Davydov, D. V. Fursaev, V. A. Tainov
Equations of motion of null cosmic strings near black holes, or other massive sources, are solved exactly in the weak field approximation. The stress-energy tensor of a null string…
Discreteness of dyonic dilaton black holes
E. A. Davydov
We show that there are two classes of solutions that describe static spherically symmetric dyonic dilaton black holes with two nonsingular horizons. The first class includes only t…
Comparing metric and Palatini approaches to vector Horndeski theory
E. A. Davydov
We compare cosmologic and spherically symmetric solutions to metric and Palatini versions of vector Horndeski theory. It appears that Palatini formulation of the theory admits more…
HYM-flation: Yang-Mills cosmology with Horndeski coupling
E. Davydov, D. Gal'tsov
We propose new mechanism for inflation using classical SU(2) Yang-Mills (YM) homogeneous and isotropic field non-minimally coupled to gravity via Horndeski prescription. This is th…
Dilaton-scalar models in context of generalized affine gravity theories: their properties and integrability
E. A. Davydov, A. T. Filippov
Nowadays it is widely accepted that the evolution of the universe was driven by some scalar degrees of freedom both on its early stage and at present. The corresponding cosmologica…
